About this 3D model

The original holder for the z-Axis-Stepper-Motor is a plain aluminium bracket. This bracket let the motor move a bit in z-Axis direction. This movement causes wiggles on the z-Axis of printed objects, because some layers gets compressed and others expanded a bit. With the new motor holder these wiggles are gone :) The original inspiration came from a post from "edirol" in the Velleman support forum. Thanks to him. I redesigned it in openSCAD because i wanted to use M3 nuts and bolts to assemble to two parts. You need * 4 times M3x12mm screws and 4 times M3 washer to mount the motor * 4 times M3x20mm screws and 4 times M3 nut to assemble the two pieces together * 2 additional M5x12mm screws and 2 square nuts to bolt the assembly to the printer frame. More details on assembly and the used nuts and bolts can be found inside the openSCAD file. update: I added a shorter version to react on the comment. This has a 12mm shorter baseplate and should work for the original heat bed configuration. Thanks for the remark on this. Print long and prosper.
