Summary

Replacement gear for the motor side of the extruder of the RapMan 3D printer.
This gear is meant to pair with the original gear of the extruder.
I made this as a replacement for the original gear that broke.

This gear uses the same teeth of the http://www.thingiverse.com/thing:4472.
I've placed the nut hole so that the screw will hold the motor on the chamfer instead of the round part of the axis.

Note:
The SolidWorks file was created on version 2008
Note2:
This gear was inspired by ( and made using ): http://www.thingiverse.com/thing:4472

Instructions

Just print and fit the screw and the nut that came with the original gear.

I've tested this printing with the 0.25 PLA Fast profile only.

With his gears, chylld reported that PLA gets soft from the motor heat, something you might want to watch out for. It would be interesting to hear whether the same happens to you.

The gear I was using before was made of PLA and I didn't have any problems ( with melting ) ...But I will keep an eye on it, thx.

Is this an improvement on the Silent Repman extruder Gear?

No. This one have the same teeth of the http://www.thingiverse.com/thing:4472http://www.thingiverse.com/thi... but has a larger hole for the motor axis ( the other didn't fit my motor, so I had to drill a larger one ). Also, now the screw holds the motor on the chamfer instead of the round part.
