Using the same OpenSCAD code of kitwallace’s from yesterday, today we made a Mobius-like solid whose cross-sections are triangles and whose boundary is the trefoil knot – that is, the knot…
Today we did not print an umbilic torus. But we did print a triangular-cross-section mobius strip, which is very close. In yesterday’s post we wished for a way to remesh…
Today I spoke with jamesford007, a student at SUNY Geneseo who is spearheading efforts there to bring 3D printing into the study of mathematics. He shared with me his technique…
A student in my GSCI 104: 3D Printing class built a catapult that prints in one piece! Inspired by zheng’s multi-piece Seej Catapult on Thingiverse, zackowen built a new Print in Place…
Gyroscope time is going to go on for a while! Today we used the Custimizer version of althepal’s Another parmeterized gimbal to make a 6-hoop version and switched filament partway through to get…
I don’t know why, but I haven’t had much luck 3D-printing gyroscopes – either from Thingiverse or that I designed myself. It really shouldn’t be that hard, but somehow the…
We are going to be printing a lot of Menger-type objects, I think. Today’s is a level 3, sliced to reveal the stars. Model again by owens on Thingiverse. Here’s…
Thank you, owens at Thingiverse! You have made the impossible possible. It was great fun walking this print around the math department today, since everyone there knows just how difficult it…
This is what happens on the first day that an 11-year-old girl and an 8-year-old girl learn how to design 3D models. The first day! I look forward to the…
At our house we have enough extra hex tiles to play a five-person Catan game, but not a fifth set of pieces. Today we printed a new full set of…
