Bed Leveling Knobs

thingiverse

These are absolutely fantastic! I wish I had discovered these sooner. I got tired of wrestling with those minuscule, hard to turn aluminum thumbscrews for bed leveling. These new knobs are a breeze to grasp and turn, and their wider design likely makes them more accurate in fine tuning adjustments. I've been using 3mm nuts from Home Depot. The STL file should be printed with a hex-shaped hole facing downwards on the bed. On my Folger Tech printer, I had to tilt the limit switch about 30° downward because the new right rear knob was obstructing the bed travel.
