Updated 2017/08/22 with thicker walls and smaller inside hole to provide better seating for the damper and extra strength
This is a spacer to allow the installation of a stepper damper on the Z-axis of the Wanhao Duplicator 6 / Monoprice Maker Ulitmate.
It replaces the standard spacer and gives 6mm of space to allow the fitment of a standard damper from ebay etc.
I recommend printing with high infill to provide strength as it will subject to compressive forces and any flex will affect print quality. It's not very big so the print time won't be too long anyway.
You'll need to add 2x M3x20mm screws and 2x M3x5mm screws to do the mod.
The short screws attach the damper directly to the motor, and the long ones attach the motor to the machine, with the spacer between the damper and printer frame.
I have provided the spacer for the damper (-6mm version) as well as a standard size version so you can modify it to fit your own particular damper if needed.
I've supplied STEP and Rhino 3D (.3dm) files so you can remix and stuff if needed. Just be cool and credit me somehow. :)
