Z top mount to reduce z-wobble from bent or misaligned threaded rods. Has a thicker rod press fit to decrease linear rod movement. Also included top mount with attached 27mmx40mm 5mm-thick plate for extruder or miscellaneous mount. Blender files included.
Last picture demonstrates difference in z-wobble between two prints
Check printing orientation, there is a flat side which should be on the bottom. For other side mirror the part for a working press fit.
Designed to be a support-less print, but configure to print the top surface well to avoid pillowing.
May need some handling/reshaping. Slightly oversized press fit mount to account for x-y misalignment from z-wobble.
