Gridfinity iFixit Mako Unit

This is a 3x4.5x3 iFixit Mako unit for Gridfinity. It's designed with a detachable rack meant to hold 9x of these 1x0.5x1 half-width bins by @HuMa https://www.printables.com/model/640797-gridfinity-ultra-light-bins-plain-half-grid-editio with the end goal of padding out the bin to a full 3x5, maximizing space and giving some handy bins for temporary screw storage. If you have some half-width bins already in your grid, then the rack is removable. I printed with PLA, which gave near-perfect tolerances/spacing for the rack inserts. I'd also highly recommend using ironing, as the top surfaces look very nice. The included 3mf file includes the bin itself, the rack (and some necessary supports), as well as 9 of the recommended half-width bins. A separate model for the bin and the rack are available as well. Note that the bin has 3 holes which might be cosmetically displeasing; I'll upload a version without these holes eventually. For now, they can be removed in FreeCAD by simply
