Veritas Famula 5191- Stitch selection knob

thingiverse

For years now, I've been itching to get my mom's heirloom sewing machine up and running with all its original features, but two weeks ago something sparked - I got my hands on a 3D printer and suddenly I'm bursting with creative ideas. I took apart and fixed the sewing machine myself, so I knew I could rely on my own judgment to create a few essential parts in Fusion360. After all, it's not like I'd need any expert help to get this project off the ground. The cam teeth component is designed to be highly modular - just take a look at that 19.5mm square knob that fits neatly onto the 20mm square negative on the selector wheel knob. If something goes wrong, all I have to do is print out a new cam part and I'm good to go. To give my creation an extra edge, I added some post-processing techniques - I superglued the teeth together to create a reinforced layer, then sanded down the dried glue for a smoother surface. The more polished it looks, the tougher it'll be to move those inner teeth around.
