Roller Switch Z probe

thingiverse

This work-in-progress Z probe capitalizes on a roller switch's inherent springiness, keeping the probe in the "up" position post-bed leveling. Updates will follow upon printing and testing. For assembly, insert 3mm shaft through bottom hole (drilled slightly), adding a nylon spacer on the other side before pushing it through the top hole. Position switch, securing with holes or hot glue for adjustable height. The probe's height is regulated by spacer placement: low enough for shaft insertion but avoiding hotend crashes. Better action photos to come. Originally, a magnet was considered but deemed unnecessary.
