I made this design to make smysnk 's gamecube controller wall mount compatible with grid wall systems. Specifically 1.8" (measuring from the outer edges of the bars. However this functionally acts as a mountable surface for anything glue-able or with compatible screw holes. I'm using random hodgepodge screws laying around the house but the holes are 3mm wide for reference. This can easily be edited to be able to orient sideways for other applications(which I may do myself if the need arises and update this post). I'll also be posting the GameCube Adapter Caddy pictured in the cover photo.
