Protect your motion system from bumps and vibrations during transport, hold your bed in place, or just hold tension on that gantry while you assemble!
These fit 2GT (2mm pitch) belts (both GT2 and GT3 - yes, it's confusing that these are both 2mm pitch! These will NOT fit 3GT (3mm pitch). Blame Gates for a silly numbering system).
Choose the STL corresponding to the belt width and pulley size of the belt run. You will probably want at least one per stepper. Mount by sliding the belts into each side, helping them over the retention tabs at each end. To remove, spread the belts slightly to help them out from behind the tabs.
NOTE: these provide a “soft lock” because they can rotate somewhat between the belts - how soft depends on the belt tension and the width of the lock print. If you want a harder/stiffer lockup, try using more than one per belt run and mount them near the pulleys.
PRINT SETTINGS
Print in any material you like. I suggest 0.1mm layers, 1mm shell thickness, and 20%+ infill, but do what you want. No supports needed. 0.1mm layers are more important for the optional hang tag. Attach the tag with something string-adjacent!
