I have just spent the past ~45 minutes designing a 36 tooth ratchet gear. The 36 tooth gear is the smallest gear that comes with holes. Making this thing was an absolute nightmare, and isn’t worth it, in my opinion. It is quite thick, coming in at around 1.8 inches. It should theoretically work but isn’t really viable. If you ever find yourself in a situation where you absolutely need a 36 tooth ratchet gear mechanism, here it is. The rubber bands pulling the ratcheting mechanism are on the bottom side of the gear because of the low space. This does require some wacky screw jointing and nut placement. Also, I used the hex screws in the cad because that’s all I had, but I’d recommend using screws with a flat head(preferably a flat head counter sink screw) Anyways, here’s the cursed build.
if you want a good ratchet at that size thats easy to build 315 made one during TP season that was p low friction and ik took at least 2 motors of torque and food effeciency and i made one but its hard to make but it is worth imo as u can blow on it and it spins p fast(i have one that survived 4 motors of torque). both of these can be found on VTOW(idk what the discord server is called anymore)
