Description

A derivative of the classic, and hopefully an improvement. Fishbone gears are known to make less noise and have less "play" as they turn, with no "give" when they begin turning as normal gears do.

This was kind of an experiment. I've never held or seen Wade's original extruder in my hand, so hopefully this is an improvement. Give it a try, but be warned that my STL exporting plugin doesn't play nicely with scale. If it's coming out the wrong size for you, look here for reference: (the original!)

hmmm....

Let us Fishing together :-P

Netfabb is free and can meassure (distances, circle-circumfences,...), scale/... and automatically + manually repair meshes.

That should help.

yep. this looks like the STL files are really big. Too big to fit on a makerbot platform. I'd recommend not printing them unless you know exactly how much to scale it to.

Are these teeth hypercycloidal or involute?

I'm not sure what you mean...I cut the gears in two and turned each half a specific amount with some math involving their height and the number of teeth. I did this by hand.
