I designed these spacers to keep Vectrex cartridges centered and protected in the most common universal game case. It has not been tested in every iteration of the UGC.
The original (left) will keep your game centered and protected somewhat but it won’t take much of a drop without cracking.
Because I needed something more durable during shipping I created the newer one (right). It is deeper but takes about 40% longer for me to print.
