This was so fun to design and build! The septafoil (7₁) knot-inspired marble track just wants to exist. The same curves that make a good rolling path also happen to print clean. The 8mm prints in place with no supports at all. I suggest…
A rocket with a printed launch spring — one piece, printed in place, nothing to assemble. Stand it nose up, push the rocket down onto the button until it bottoms out, then let go. A printed spiral coil fires it 3–7 inches straight up!…
We made this belly-up cat for Sparrow. Three dozen iterations later, the curves are finally right—your thumb drops into the tummy dish and just stays there. It prints in an hour with zero supports. The absolute most important setting: do…
A push-button fidget with a real return spring — printed in place, one piece, nothing to assemble. Push the button and a ball on a serpentine spring clicks over eight sharp teeth; let go and a printed spiral coil pushes the whole thing…
Sibling to the septafoil, and this one was more fun to solve. Same idea — a closed tube with a bore running through it and a slot along the outside narrower than the balls, so they live inside where you can see them and never come out.…
Seshat is the Egyptian goddess of measurement, geometry, architecture and the written record. She's the one holding the other end of the cord when a temple's foundations were squared to the stars. Prints flat on its back, no supports,…
A box that twists shut, shaped by one line of algebra from 1770. Set the lid on, turn it thirty degrees clockwise, and it clicks. The line is Vandermonde's difference product, which he read to the Paris Académie in 1770; square the three…
