US General Mini box double stack adapter

This is a 1 hour print to get a set of 4 adapters that allow you to stack 2 harbor freight mini tool boxes. Be aware that the older tool boxes do not have holes for feet. At minimum this required 1 of the newer boxes, preferably both newer. In the future you could use the holes to index a wheeled platform so the mini tower looks like a proper roller cab. Uses 2x6 mm cylindrical magnets press fit. I used 7 magnets per adapter, but you could use less or more. next iteration may include a spacer to prevent any fore to aft sliding. As printed there is 0 left to right play, but the qc on the boxes might require some hand fitting if yours line up differently,
