About this model

When you want to tram the print bed of a Bambu Lab printer to improve bed leveling, you have to adjust the knobs underneath the bed. These knobs can be quite difficult to turn because they can be tight and you hardly have any grip due to their twelve-sided shape. Also, the wires for the print bed can be in the way when trying to turn the knob in the back.This tool fits like a glove on these knobs and makes turning them completely effortless. Depending on how accurate you can print these, you could print 3 of these and put them on all knobs while tramming so you don't have to keep switching it around. (Don't forget to remove them when finished, as the bed might not have enough clearance if it moves all the way down!!)I have added two versions: one where the part that fits on the knob is 0.8…
