CoreXY Z Axis Carriage for Delrin nut (4 hole, 8mm lead screw)

thingiverse

This is a Z Axis carriage modified to take a Delrin nut, for use with an 8mm lead screw. I love starrysky's design, but I wanted to have 2 z-axis lead screws instead of just 1 5mm threaded rod . I had to extrude out one of the faces so that it presents a flat surface that will connect to part 2040.stl. I added M3 screw holes on both the top and the bottom so you can choose to put the nut on top (pull) or on the bottom (push). Print Settings Printer: Custom i3 2020 Rafts: Doesn't Matter Supports: No Resolution: .175 or .2 mm height Infill: 35% Notes: Normally I would use supports with this model BUT trying to dig support out of those m3 screw holes is ridiculously hard. Instead I relied on my printer's bridging, which I had to set to 80mm\s - worked out well for me.
