Kinda crummy, I should improve the fit on these as the spools love to tilt around. it's a 2x4 box that holds some wires with some relatively tight holes to thread them through. I thought it was kinda neat tho.

Built the CAD lazily right on top of someone's Solidworks implementation of Gridfinity boxes, so that is why the SW file is a big mess. https://www.printables.com/model/174152
