Are you tired of wasting those small spools from sunlu well make them into organizers helps hold loose bolts and other small items everything you need to make these is included you don't really need the drill guide I put that in their just in case I just used the cubby itself to guide my drill. you might need to adjust tolerances so try a test print on the drill guide if your not sure see if your screws go through. Mine I threaded through the Cubby so I didn't need to put a nut on the bottom if you want to do it a little different that is fine but you might need a nut on the bottom side if you add more tolerance or drill it out a little
