The STL is for GT2 belts, but the openSCAD file is included so you can modify it for other sizes.
Belt ends are looped through two printed blocks positioned so that they are within about 1". The belts are held in place using removable printed clips that force the belt's teeth to lock togoether when doubled over. Bolts are passed through the blocks, and the belt can be adjusted by tightening the bolts.
The design does not depend on tooth spacing (just that there are teeth). Only the belt height, width, and doubled height should need to be adjusted for other belt sizes.
