Vernier Caliper Holders for bed leveling (works with any 20mm v-slot extrusion

thingiverse

This holds a standard vernier caliper in place as a bed level gauge from the gantry arm, requiring manual adjustment to ensure accurate measurements. To take side measurements, the caliper must be moved past the nozzle, whereas it remains stationary for front and back assessments. For secure attachment to the extrusion, t-nuts are necessary, which can be threaded into corresponding holes. Additionally, two set screw holes accommodate m3 screws for further reinforcement.
