Prusa MINI Silicone Bed Leveling Mod - locknut sanding jig

Supplement tool for this: https://forum.prusaprinters.org/forum/user-mods-octoprint-enclosures-nozzles/prusa-mini-silicone-bed-leveling-mod/

If you cannot get low profile M3 locknuts for Silicone Bed Leveling Mod, you can still use standard M3 locknuts and sand the middle rear one to 3mm height.

This simple jig helps to grab the nut while hand sanding, protruding the correct nut height to be sanded off.

Simply insert standard locknut (nylon side inside), secure it with one of the torx screws you have prepared for the mod and thats it.

Hand sanding takes only five minutes.

Hope this simple jig will help you avoid headaches from looking for low profile locknuts supplier.

Happy sanding!

0.4mm nozzle recommended
