Z Axis Endstop Adjuster for Rigidbot

thingiverse

This is a modified version of mikedifilippo's original design, accessed through http://www.thingiverse.com/thing:362662. I faced issues with printing the initial part so I fortified it with additional plastic to compensate for its fragile state. There exists one notably thin area on the wall which may still prove challenging to print; a quick trim resolves this problem entirely, rendering the piece fully functional. The switch attaches firmly onto the bearing holder using a shorter m3 screw, whereas an elongated, wider-screw (M4 or 6-32 alternatives work well) securely fastens the adjuster in place. Upon occasion that these holes prove insufficiently precise for proper assembly, drill and/or tap to accommodate slightly snug fits with your preferred adjuster screws. One note: To correct misaligned orientations of limit switches, remount them according to modified instructions which ensure exposed surfaces – take particular attention from comparisons outlined on page 7 of Rigidbot user manuals paired with depicted illustrations showing these configurations.
