If you know me, then you know I can get easily distracted. This was the case with this project, where I set out to test the Chebyshev straight line mechanism which is part of my much larger Rube Goldberg Project, and ended up with a gravity powered looping ball contraption. The main challenge was designing the escapement, which I was able to do with the help of this app: motiongen.io (Not sponsored, but really great)

I also have a patreon: patreon.com/engineezy

Much of this project was printed on my Bambulab X1 Carbon which I HIGHLY recommend (seriously, nothing beats it) Here’s my affiliate link:

Also, the electric screwdriver I used to assemble and disassemble this thing many times is a game changer: geni.us/f6oJ
