New z-Motor-Holder for the Velleman K8200 or 3Drag

cults3d

The primary holder for the z-Axis-Stepper-Motor is a standard aluminum bracket. This bracket allows the motor to move slightly in the z-Axis direction. Movement of the motor causes wiggles on the z-Axis of printed objects, because some layers get compressed while others expand a bit. With the new motor holder, these wiggles are eliminated. The original idea came from a post by "edirol" in the Velleman support forum. Thanks to him. I re-designed it in openSCAD so that I could use M3 nuts and bolts to assemble the two parts together. You need 4 times M3x12mm screws, 4 times M3 washer to mount the motor 4 times M3x20mm screws, 4 times M3 nut to assemble the two pieces together 2 additional M5x12mm screws, 2 square nuts to bolt the assembly to the printer frame. More details on assembly and used nuts and bolts can be found inside the openSCAD file. Update: I added a shorter version in response to comments. This has a 12mm shorter baseplate and should work for the original heat bed configuration. Thanks for pointing this out. Print long and prosper.
