Replacement spur gears for Capsela worm gearbox

thingiverse

**Update:** Too much friction prevents the motor from turning, and I'm still trying to figure out what to do about it. The two smallest gears in the Capsela worm gearbox seem to fail frequently, including replacements for them. This also includes a slightly larger replacement for the spur gear that interfaces with the worm, intended to reduce play. However, this might make things too tight as a result. My printer has loose tolerances, so you will likely need to adjust sizes for your own printer. I've yet to find an effective way to open the gearbox. Ultimately, I had to cut it with a rotary tool and reattach it using glue, which was unsightly. If you know of a better method, please let me know.
