Summary

Who doesn't like the biohazard symbol? The hex is deep enough so a washer can be placed between the gear and bearing. This helps the gear clear any protruding screws.

Instructions

The attached .skp has the hex head socket oversized by .4mm. It's a little looser than I expected but works well. Printed @ .2 layer height and .4 infill.

I use this on my prusa I3....works great for me!
Thanks for the great work.

Is this for a Printrbot LC? I randomly came across this on yeggi(??) rather than a search here on Thingiverse.

It'll work on any printrbot.

When I slice this it only does the small gear and a dot at what looks like it ought to be the center of the large gear. It looks good when I drop it into Repetier then goes wrong on slice.

Ideas?

Not sure. It slices well with slic3r 0.9.8. I've seen that happen when objects aren't on the same plane but they're definitely coplanar. Try breaking up the print so they're treated as two distinct objects. It may help to print them separately anyway. I find the pinion gears tend to get a ridge at the height where the spur gear ends. It's probably due to the time between layers speeding up.

Thanks for sharing..

This is sweet! Thanks for posting.

I love this! I was thinking of making a similar design... Now I'll have to try harder to be original!
