Figured out how to make gears in OnShape today using their featurescript. I am now officially unstoppable. 3d printing them now. This is just a hacky test job (those spokes on the largest gear are bad... I made them with a pattern of holes rather than an equal width spoke)

Tne featurescript is great. It can also make helical gears, but I suspect 3d printer will struggle to print them unless the angle is fairly mild. But will try anyway.

Worst gear train ever. Also my first gear train ever. Now to make up some cunning mechanisms.

The thin stem was to hold a slider to connect to the gear with a connecting rod, but idea didn’t quite work. Slider rod not long enough and too much friction everywhere.

Idea is prototype of part of a mechanical sculpture. The slider would move a pen over moving paper roll drawing a sine wave. Paper roll would be moved by a bevel gear pair coaxial with smallest gear. Something like this.

If I can get the mechanism working smoothly, add a motor that goes one round when turned on, then turns itself off with a limit switch somehow, giving you a single sine wave printout. We’ll see if I finish this mechatronic art crapject or run out of patience or skill.

Doh! My idea needs a bit of rethink. I wanted a framed sculpture that spits out a scrap of sine wave each time you push a button so art viewer can take away a tearaway souvenir. But doing that with a pulling motion will be tricky. Like a bathroom paper towel dispenser. 🤔

How is the tension maintained on the paper? feels like I'm missing something here.
