Prusa i3 Mk3 DTI Mount

thingiverse

I required a trustworthy method to measure and calibrate the Prusa i3 Mk3 bed so created this DTI Mount. It fits snugly around the extruder motor and magnetically secures a 57mm diameter DTI as close as feasible to the extruder. The design encloses all but the extreme right side of the bed, allowing me to achieve within a 0.05mm tolerance (utilizing shims) before applying the firmware bed levelling routine. Once manually and firmware calibrated, I observed an immediate enhancement in first layer adhesion and layer consistency across the bed even when heated to 85C. Something I could not accomplish when relying solely on the firmware bed calibration routine.
