Printrbot Simple Bed Leveling Screws

thingiverse

Bed leveling is really important, but something I always hated. Everytime I wanted to level my bed, I had to look for the allen wrench and then hold the nuts at the bottom so they wouldn't turn. So I made some knobs and nut plates. The knobs are easy to turn without any tools. And they have a little dot on them so you can, for example, turn them all 1/4 turn in the same direction for small adjustments. The nut plates hold the nuts so they won't turn. Now leveling my bed is almost fun. Instructions Print out four knobs, and two of each of the nut plates (Nut_and_spring_plate and Nut_and_spring_pate_2 are slightly different). Each plate has a notch near the nut hole designed to clear the zip ties on the front of the carrage, which is why you'll need two of each. You'll need to replace the normal M3-20 screws with slightly longer M3-25 screws, and you'll need four extra M3 nuts. Place the M3-20 screws through the top of the knob, and then add an M3 nut to hold the screw tightly to the knob. Slide the nut plate onto the carrage and then hold an M3 nut underneath while you screw the knobs/screw combination in place.
