What is this?

This is a mod that allows you to use 20-tooth idlers instead of 16-tooth idlers (or flanged bearings) on your Duender. Maybe you have some leftover, maybe you just ordered the wrong ones like me :-D

And it replaces the big M8 screw on the back mount by M3. You actually just need to reprint the top part and can leave the motor holder itself as-is, instead just printing a little plug for the hole.

What do I need to print?

This mod replaces the parts called "X-Mount 1/2 Left/Right" and "Y Left/Right Motor 2". The main motor holders ("Y Left/Right Motor 1") can be kept. Print each part once

How do I assemble this?

For the parts on the motor, insert a heatset insert into the spacer from the bigger side, also add a heatset insert into the plug. Then, put the shims and idlers on as usual. Then, add the spacer / plug on the inner screw

For the parts on the X-Axis, the process is the same as for the regular 16T version.

Acknowledgement

Many, many thanks to Sergei for his incredible work on Duender!
