Caliper holder for bed leveling Anet A8

thingiverse

Simple trick to level heat bed with digital caliper. I used it on all four corners to level the bed and let autolevel fix the rest, worked great for me. Set jig on rods, insert caliper. Slide bed so you can push caliper down to heatbed corner, take measurement. Check all corners till you get same measurement on all four corners. I made three rounds to get within 0.05mm on all corners.
