Single Start Z Nut Mount (V1.1)

thingiverse

I ordered this stepper http://www.banggood.com/JKM-42mm-Hybrid-Two-Phase-Stepper-Motor-40mm-Length-For-CNC-Router-p-1011710.html. The lead screw is 8mm single start, meaning the thread pitch is only 2mm instead of the 4mm with the motor specified by Tech2C or the more common 8mm (four start). Unfortunately, the Z_nut_mount_v1.1.stl wasn't suitable because the lead screw nut has only three mounting holes. On the positive side, the nut mounting holes are threaded for M3, so you can put the nut on top of the mount and use M3x10mm screws through the mount to secure it in place. Note: I remixed the V1.1 Z-nut-mount before receiving the motor. When the motor arrived, I realized that the z-nut couldn't fit the mount because there wasn't enough room between the mounting holes and the center shaft of the nut for either screws or nuts. As the Z-nut mounting holes are threaded for M3, I came up with this remix.
