Spool gear for filament winder

thingiverse

I developed this spool gear to fit a variety of spools, as I have spools from multiple sources lying around. The gear is the same as the spool gear on the filament winder by Ian Johnson, with a few adjustments and a cone that starts at 50mm and goes down to 20mm. I have designed a replacement hall effect holder but it's still a work in progress. The bearing holding portion needs a little bit of work, because the bearing is loose by a hair or three. Instructions Assembly includes: 1 5/16 or 8mm threaded rod 1 608zz skate bearing 4 Fender washers 3 5/16 or 8mm nuts The bearing holder / hall sensor mount is designed to fit the Cheap-o hall effect sensor. The magnets are 12mm magnets from a local craft store. I have yet to mount this to the board yet, but I wanted to share this work in progress.
