Description
This is my model of TARS from the movie Interstellar. TARS body consist of 4 legs, this model uses magnets to form joints and keep everything together. The magnetic joints slides along the full leg length which makes for a very flexible and expressive model.
Quick overview:
The model files are in the recommended orientation and should be easy prints. Inside each leg are slots to hold magnets. A pause print must be added at the top of the slots for inserting the magnets.
The TARS text and braille is easy to fill in with a marker pen (I used metallic gold + red).
I used 6 mm diameter, 2 mm thick neodymium magnets bought from Amazon. Since they are quite small, I used them in stacks of two for extra holding power. Bigger is probably better, the slot fits up to 4 mm thick magnets. Each slot should have two magnets for more stable legs (12 in total), single stronger magnets might also work (6 in total).
All magnets should be inserted with the same polarity direction in every slot. This is very important as otherwise the legs would repel instead of hold together. I printed one leg at a time to reduce the risk of mistakes. This is what it should look like before resuming print:
TARS has two monitor screens on the top center legs. I used screenshots from my own terminal and printed on photo paper (see the zip file). The photo paper is cut to size (16 mm x 15 mm) and attached using double sided tape. The lower legs also uses the photo paper but just plain black.
Let me know if anything in the instructions is not clear. Good luck.
