X-Max Z Rod and Motor Bracket

thingiverse

Redesigned rod and motor bracket for the Qidi X-Max (may also work on X-Plus, but have not confirmed dimensions). While installing tighter tolerance polymer bearings for the Z rods the stock molded parts were found to have the wrong pitch. The upper metal plate and bed platform both have the rod to rod spacing at 180mm, while the molded parts were over 182mm. This led to the bearings binding very badly over the travel distance. New printed version is a drop in replacement and should fit without issue. Be sure to measure final parts to make sure they are accurate. Print in a stiff, non warping, material. High temperature not required. STEP and Fusion files included for easy modifications. Note: This version has a small hole at the bottom of one of the bearing sides to facilitate new type of limit endstop. If a completely sealed version is desired modify the original files.
