PrintRbot + 2.1 Digital Micrometer holder

thingiverse

This cheap micrometer on Amazon ensures precise adjustment of your print bed. Made in the USA, it prints two parts and takes 2-5 minutes to level your bed within ±0.02mm. Ensure the bed is heated beforehand to prevent warping. Set Z at around 10-20 for minimal stress. Adjust Y up and down until consistent results are achieved across. Repeat on the other side, and you're done! You'll need four M3 bolts (25mm+) and optional M3 nuts to secure it. Be sure to identify which position your device snaps to, and keep the extruder as far away from the snap points for accurate results. Check out this Amazon link for the electronic digital indicator/depth gage. The inventor file is included for printing convenience.
