This is a simple rack to mount to the wall and hold your spools. One side of the spool is supported by the wall, the other side rests on the wood dowel. Mount the brackets to studs using a 4' dowel you should hit the studs on both sides. The center hole is 34 mm (or 1 1/4" dowel).
Print with 50% infill for a good strong part at .2 or .15, I will use triangular in fill on mine, currently I can not print this file lol, but I have measured and planned it out and it works well. The brackets are about 6.5 inches out from the wall to the center of the hole, that seemed to be the sweet spot on the rack to rest on the dowel and wall easily.
