Introduction

The RepRap Haeckel is an open source 3D printer that uses fused deposition modeling (FDM).

Ernst Heinrich Philipp August Haeckel (* 16. February 1834, † 9. August 1919) was a German biologist who promoted and popularized Charles Darwin's work in Germany.

The Reprap Haeckel is based on a generic Mendel. Its goal is to be a self contained unit, that can easily be upgrade to have a Heated Build Chamber. The idea is to have a very rigid frame and x assembly that can withstand light milling, such as PCB Milling or wood engraving. The Haeckel has two integrated spool holder, each holds up to 4 filament spools (9cm wide each).

Printed parts

Assembly

1. Overview	2. Begin by sliding a three way connector on a 420mm extrusion
3. Slide the connector down and tighten it	4. Take a small corner and attach it
5. Take a second small corner and attach it to the other side. Repeat Steps 2 - 5. You should now have two of these front struts.	6. Attach one 430mm Extrusion to one of the three way connectors. Attach Y-Motor mount and two bar clamps as pictured.
7. Attach the other strut to the horizontal bar. Make sure the Motormount and bar clamps are correctly attached. You will not be able to insert nuts into the t-slot afterwards	8. Take two 430mm extrusions and attach them to the top and bottom corners. The motor mount gets attatched to the bottom extrusion
9. Make sure the frame is rectangular. The measurements can differ by the type of extrusion you are using. This measurement is 470mm and needs to be exact on all points	10. The distance between the lower extrusions needs to be 50mm (center to center). For 20mm wide extrusions its 70mm (outside to outside)
11. The front side of the Haeckel is now done and square	12. The back side is very similar to the front side. Assemble a frame as pictured. Vertical struts are 550mm (longer because they carry the spoolholders). Horizontal struts are 430mm. Check steps 2 - 5 for details
13. Insert nuts into the lower extrusions. You'll need 5. 2 for each bar clamp. One for the belt tensioner. Assemble small corners at the bottom. Check the measurements on this part aswell	14. Assemble bar clamps and belt tensioner to the backside. Attach 3x 430mm extrusions as pictured
15. Attach 3x 430mm extrusions to the other side aswell	16. Attach Z motor mounts to the bottom. NOTICE: if you wish to mount any electronics to the inside of the printer, you will need to insert the nuts now. You will not be able to install any nuts into the t-slot lateron. If you forget this, you will have to disassemble the whole printer lateron
17. Attach the front frame. The overall frame of the printer is now finished. Check if its square
18. Parts for each end of the x axis. I recommend using slightly longer extrusions. I have used 90mm extrusions and its a really tight fit.	19. Assemble one bearing holder to the extrusion
20. Prepare the nut holder for the threaded rod. You will need two springs and two m8 nuts. Each nut is pushed upwards by one spring.	21. Attach the prepared nut holder to the extrusion
22. Attach the motor mount and bar clamps. This is now the x-motor end	23. The x-idler end is very similar, just replace the motor mount with the idler mount
24. Loosely attach the smooth rods to the clamps and slide on the axis-ends. Only when the axis slide freely tighten the bar clamps.	25. Attach a Nema17 stepper motor
26. Make sure the nut holder is centered and insert the threaded rod. Attach the threaded rod to the motor. NOTICE: During the build proess I noticed that this x assembly is a bit wobbly. I added more LM8UU bearings. Each side of the x axis now has 4 linear bearings. See the pictures 27 & 28.	27. Connect the two axis ends with the smooth rods. The distance between the smooth rods should be 50mm (center to center). If you are using 8mm rods, the distance is 58mm (outside to outside). Also attach the y motor and y smooth rods. You can see the mount for the ramps boad in the front righthand corner here. In the back, there is already a rasperry pi mounted - to be used with octoprint.
28. Installl the build platform. Now take a shameful look at the mess you have created on your desk.

Changes and upgrades

1. Installed a fan-controller thats usually built into 3.5 inch slots on computers. Used 20mm_extrusion_fancontroller_holder_30mmheight.stl	2. Installed various switches that control lighting on the printer. Used these switches: Conrad 700215-62, Conrad 701343-62, and 20mm_extrusion_switch_holders.stl
3. Replaced the x-axis ends with longer extrusions. The new ones are 270mm and offer much more space for the motor and other accessories (e.g. webcam)	4. Installed a PSU jack (Conrad 612600-62) with a switch (Conrad 700215-62). Used 20mm_extrusion_psu_jack_holder.stl

City rhythm - the newspaper of the city district Troitsk

From January 31 to February 2, not far from Troitsk, in the Desna health complex, the XIV International Youth Scientific Readings named after. S.P. Queen. The host country for the second year in a row is the Gymnasium. Pushkov, she organizes the event together with the RISKSAT company and the administration of Troitsk with the support of Roscosmos. This year the Readings are dedicated to two anniversaries: the 75th anniversary of the Victory and the 55th anniversary of Alexei Leonov's spacewalk. More than 500 schoolchildren, students and teachers from 25 regions of Russia and not only gathered at the conference, the anthems of Armenia, Germany, the Czech Republic, India, Belarus and, of course, our country were played at the opening. The most distant guests are from Yakutsk and the village of Cape Kamenny, which is in the very north of Yamal ... Every year a delegation from the Republic of Sakha brings a program at the intersection of science and arts. At the opening they showed the dances of the mythical
characters of the Olonkho epic, aiyy gods from the Upper world and abaakhy demons from the Lower. In our Middle World, a shaman-oyun dances, connecting us with the cosmos. The author of daring and bright costumes is
Aisara Otova, a schoolgirl from Yakutsk. And the Trinity Dance Ensemble of Galina Goleneva presented a number about the continuity of generations. A couple of kids, then an older one, and finally, a young man with a girl - this is Maria Sergeeva and Timofey Tikhonov. This is how all the new “space boys” grow up at the Royal Readings.

From Troitsk, the conference was greeted by the deputy head of the city, Valentina Glushkova, and the next day, the head of Troitsk, Vladimir Dudochkin, met with cosmonaut Oleg Kononenko, the same one who spoke to schoolchildren from orbit a year ago, and presented him with a badge of honor in honor of the 40th anniversary of Troitsk . nine0003

From Yamal to Leipzig

On the morning of January 31, schoolchildren and teachers meet in the hall as old friends. Pushkov school students greet Karolina Turanskaya and Lyudmila Shishkina from the village of Mys Kamenny. To get to Moscow, you need a helicopter and two flights, and at every transfer you can get stuck due to bad weather. “Royal readings are such a thing in which you need to apply not only knowledge, but also aspirations and a dream!” –
says Carolina. Last year, the audience applauded her poems "Take me to the astronauts." Now the girl is in her senior year, she sees her profession at the intersection of space medicine and engineering, she is going to enter the Moscow Aviation Institute. nine0003

Artyom Makarenko from Dedovsk near Moscow advises the same university. It was he, together with Pushkovite Mikhail Terekhin, who discovered a new island in the Arctic by means of remote sensing (Earth remote sensing).
“I've been at readings for five years now,” he says. “I lead a circle on remote sensing at my school, I bring my students already as a leader, and as a student at the Moscow Aviation Institute, I begin my scientific activity.”

Troitsk is familiar with the delegation from Germany. Firina Bugenhagen, Cosma Haeckel and Leander Weirich in NASA jumpsuits. Firina and the head of the delegation Ralf Heckel already visited us a year ago, Cosma and Leander for the first time. “I've been on the team for a year now,” says Leander. - For the NASA Rover Challenge, they needed a team with a boy and a girl, they only had girls, and they advertised on TV. I saw and offered to participate.” Leander is from Hamburg, Firin lives in Berlin, the Heckel family lives in Leipzig, where the team gathers every weekend to work on the lunar rover project. April 2019year in the same "challenge" the Germans took first place.

Lectures and workshops in the afternoon. IKI Deputy Director Alexander Lutovinov talks about quasars, Artyom Abunin, an employee of the IZMIRAN Space Weather Forecasting Center, talks about the Mir station, and Pyotr Termen, the great-grandson of Lev Theremin, shows how to play the theremin, plays a melody from David Bowie's "Space Oddity" (the one that in the headphones of the dummy that Elon Musk sent to Mars) and other hits.
In the foyer there are workshops on robotics from the Technospark Center for Contemporary Art, and on painting from the Gymnasium. Pushkov, and the dynasty of masters Yadne (Viktor, Inna and their son Vladimir) from Salekhard teaches bone carving. Everyone coped, even the little son of Ralph Haeckel. nine0003

Fantasy

and perspective

Saturday is the day of defense of design works. More than 120 reports in 11 sections devoted to remote sensing, the history of space exploration, NTTM, robotics, astronomy and astrophysics, space and culture; juniors and teachers performed separately.

David Kirakosyan from Yerevan dedicated his research to Alexander Kemurdzhian, one of the creators of the Soviet moon rovers. Only one detail: through the whole war, he carried a student record book in order to return and study again ... About the history and work of Karolina Turanskaya together with Lev Beregov from Balashikha. "The Antarctic Odyssey of the Space Host" is dedicated to Yuri Senkevich. Carolina was struck by the fact that the name of the main film traveler of the USSR is almost unknown to young people. And few people know that he was preparing for a flight into space, was in Antarctica ... To find out the details, schoolchildren contacted scientists, doctors, and not a single letter remained unanswered. nine0003

“Very strong works, full-fledged scientific research, it was very difficult to choose the winners,” says Mikhail Korensky, director of the CFP, IOF RAS, member of the jury of the NTTM section. “I would like to wish the guys to do more research, history is also important, but above all, their own developments.” “The level of work is different, but in general it is good that children are interested in science,” says TISNUM employee Konstantin Kravchuk, who sat in the astronomy section. - A lot of works on fantasy, perspective, little-studied topics. I was impressed by the work of Nastya Khlopenova: a fifth-grader came up with her own satellite for collecting garbage. The work of junior schoolchildren was evaluated by ISAN postgraduate student Alina Golovanova. “The children were very worried, but they performed with dignity, well done. nine0005 And it is clear that they worked themselves. One boy brought an eclipse model, others sculpted, embroidered, designed robots…”

Astronauts nearby

Last year, schoolchildren were able to communicate with the astronaut during a communication session with the ISS. And this year - with two at once, and personally. On Friday, Moscow City Duma deputy Oleg Artemyev arrived. He was asked questions from very childish ones -
was it scary when landing? -
to serious, say, about the use of 3D printers in space. It was this question that Artemyev noted as the most interesting. nine0005 Oleg Kononenko visited Desna on Saturday. Last year, while still in orbit, he implemented a creative project with Pushkov students. The idea was submitted by Olga Moroz, Deputy Director of RISKSAT. These are works based on photographs of night cities. Kononenko printed them out and arranged the first ever exhibition in space. “Conferences with children are memorable, they brightly color life at the station,” he says. - After all, we live according to a schedule - experiments, work - and children's emotions and questions leave a mark. It’s a pity, it’s not clear who asks them.” nine0003

But now you can see everyone! We talked for more than an hour, from what I remember: Kononenko would like to become a member of an expedition to Mars, but not “one way”; it would be interesting to test the new ship "Eagle", but Dragon or Starliner - no, because the commander there is only an American. Moscow and Paris from space -
yellow, and New York - white, because it has already switched to energy saving; Madrid looks like a butterfly from space, Barcelona looks like a bird with wings
, and Lisbon looks like a skull
… And our final question is: “Is it more a space game or a way to space for the children who participated in the conference?” “For the little ones, it’s a game, but for those who are older, it’s a conscious choice of path,”
answers Kononenko. - But they say that you do your favorite work effortlessly. And it’s good if the game in space turns into a hobby and a profession. Russia is famous for the fact that we have very smart, creative children. And it is Russia that, as a rule, leads the world civilization, coming up with innovations, technologies, ideas…”

WHAT BOOKS: March 2019

such nonsense:

In the new book by the historian Yuri Sushko, the genres - political detective story with adventurous melodrama. Fresh, never before unpublished facts from the personal life of a brilliant physicist are simply shocking, but outrageous immorality and "flexibility" of Margarita's life principles Vorontsova, the wife of the sculptor Sergei Konenkov, makes one doubt: yes could this be?! Alas, it could. More precisely: fortunately, it could! For love triangle and women's intrigues eventually gave Stalin a nuclear weapon, which preserved the fragile peace after World War II…

Alas, all this is a lie of pure water and impudent swindle. To Unfortunately, this book is neither a detective nor an adventurous melodrama. Rather it's indistinct sentimental biographical sketch, and just about the woman he loves Einstein, namely about the pillar noblewoman Margarita Ivanovna Konenkova (Vorontsova) you can learn very little from this book. Much more in the book talking about her husband Sergei Timofeevich Konenkov, a famous sculptor, People's Artist of the USSR, Hero of Socialist Labor. And the biography Konenkov is so extensive and detailed, with many characters who do not have nothing to do with Einstein, what do we learn about his creative activity perhaps even more than about the main character - an outstanding physicist and Nobel laureate Albert Einstein, with whom favorite woman shamelessly cuckolded her husband for ten years (from 1935 to 1945).

And Margarita and Albert had known each other for 25 years - since 1930, when they first met in Berlin, and until 1955, when Einstein died in Princeton. True, the last ten years, after December 1945 Stalin sent a ship to Seattle for Konenkov and his sculptures "Smolny", Margarita and Albert communicated remotely - by letters on mail. It remains unclear from the book how frequent their epistolary exchange and when it broke. It is obvious that they corresponded frequently during the first two years after separation - at 1946-1947 years. And then? This pseudo-historian Sushko writes surprisingly vague and inaccurate, often omitting dates and omitting important facts, and I myself did not find a single new fact, but I re-read a bunch of books and articles about Einstein and Konenkov and concocted his alleged detective book - a list literature at the end of the book as much as six pages.

Calling a spade a spade, we can safely say that Margarita was a real whore. This was her position in life from the very young years, when she ran away from her parents from her home in Sarapul and went seek happiness in Moscow. To Konenkov in his bohemian workshop on Presnya, she nailed because even though the sculptor was a peasant from the Smolensk province, but was already considered an academician of painting, sculpture and architecture, a professor who taught students. In addition, from the hungry post-revolutionary Moscow during the war Communism Konenkov hastened to flee abroad. So prudent Margarita made a good choice. She was generally quite a practical lady and organized: in the future, it was she who was looking for orders for her husband and kept track of family finances. nine0003

She cheated on her husband not only with Einstein. However, apart from Einstein, the author mentions only a few cases of Margarita's betrayal of her husband, and with very worthy persons: with Sergei Rachmaninov and Fedor Chaliapin. Perhaps there were other episodes, since Sergei Konenkov in the 1930s with went headlong into religion - joined the malignant sect of Jehovah's Witnesses. His head went so far that he almost gave up work, stopped sculpting, and only Margarita sometimes forced him to do business, distracting him from religious mysticism. She herself was often absent from home: for weeks and months disappeared at Einstein's house in Princeton or on the lake in his country house or on a yacht in Saranac Lake. nine0003

Margarita was also often absent from home and due to the fact that actively engaged in various social and charitable activities - collected funds for various aid funds for the USSR and for Jewish organizations. Jews in the United States during the war were most willing to help the Soviet allies and Jews, and Margarita collected tens of millions of dollars in aid, as well as various necessary things, clothes, medicines. In the United States during the war there were many members of the Jewish Anti-Fascist Committee (JAC) - it was a public organization in the USSR, formed by the NKVD in the early 1942 years at the Soviet Information Bureau. She consisted of well-known representatives of the Soviet Jewish intelligentsia, literature and art for propaganda purposes abroad. For this they paid the price. The head of the JAC, Mikhoels, was killed by the NKVD in Minsk in 1948, and then all members of the committee were repressed, and the organization was destroyed, although, as the author claims that many members of the JAC were active agents of the NKVD. But in during the war, they regularly communicated with Einstein and Konenkova, and together with Margarita traveled with performances to US cities, Mexico and Canada. And sometimes they collected large halls and stadiums, where a box was passed around the circle to collect donations. nine0003

Margarita even before the war (when exactly, the author is silent) was recruited by the secret services of the USSR. Then in the USA it was led by NKVD resident Elizaveta Zarubina (Rosenzweig), famous for finding and handing over to the security officers the famous Yakov Blumkin (from Julian Semenov, he was the prototype of the young Stirlitz), who was hiding in Istanbul. Stalin knew about Margarita, who tried to lure Einstein to the USSR after the war, but nothing came of it: Einstein then already understood that the USSR was a prison. And when, before the war, Einstein wanted to emigrate to the USSR, he refused him: “This Zionist is more useful if he stays in the USA,” allegedly Stalin told Lavrentiy Beria. nine0003

Margarita collected information about the creation of an atomic bomb in the United States. Thanks to communication with Einstein, she was familiar and often communicated with him at home. many prominent physicists: Robert Oppenheimer, Leo Szilard, Enrico Fermi, Klaus Fuchs and others involved in the Manhattan Project. They visited Einstein at Princeton and corresponded with him. Moreover, the author hints that Margarita had a particularly close relationship with the scientific director of the Manhattan Oppenheimer's project, since he was more interested in Soviet intelligence than others. She managed to get Oppenheimer to take on the project and push through through the security service, several young European physicists who were recommended by Moscow: they either had left-wing views or were already recruited by Soviet intelligence. nine0003

Although Margarita did not understand anything in physics, she diligently wrote down from memory all the new and incomprehensible words that sounded in conversations physicists, and also sketched, without understanding, the drawings and diagrams that they showed each other. Of course, Margarita did not give Stalin the secret of the atomic bombs, because American intelligence officers suspected Albert Einstein of left-wing views and connections with the communists, they considered him disloyal, and for this reason was not allowed to participate in the Manhattan Project. Einstein never was at Los Alamos and other secret nuclear laboratories, but he had personal connections with many of the physicists involved in the project. Information about it project for years came to the NKVD from many sources, including after departure of the Konenkovs from the USA. And Margarita also had the opportunity to see at home Einstein at Princeton, correspondence and personal notes and papers. Author claims that she hated her handlers from the NKVD, who constantly patronized her in the United States, setting goals and pushing her to a more active search for secrets. About us relieved she left America, as this meant the completion of her immediate and dangerous intelligence work. But the NKVD was also watching her in Moscow, tracking her correspondence with Einstein. nine0003

By the way, Einstein was a very loving faun, albeit without hooves. Margarita was far from his only mistress. He had two official wives - in Zurich, Serbian Mileva Marich and in Berlin, Elsa Einstein, his cousin, by husband from Löwenthal's first marriage. It can be said that Margarita was his third unofficial wife, who did not divorce her dense Russian husband who went crazy on religious grounds. The author claims that Einstein also had a rather close relationship with his personal secretary, Helen Doukas, who accompanied him from 1928 years until death. When she was younger caused jealousy and anger of Elsa.
