A replacement back for a dial indicator that lets you mount it to the X axis rail of a Kobra 3.

It is designed for an inexpensive WEN model, but based on some other models I tested, should work for the popular Clockwise digital model or others with the same 33.5mm screw spacing.

This can be used to check the bed level, as demonstrated in this video.

I printed in PLA, but I would expect it to creep and loosen its grip over time if attached for too long. PETG or ABS/ASA would work better long-term.
