This design is custom made by me. It can hold so many damn things. You can most controllers like the NES, SNES, SN30 Pro, Pro Controller, Xbox Controller, and many consoles like the NES Classic, SNES Classic, Vita, and the Nintendo Switch. Most things fit. The gamecube controller does not fit though, I should point that out, and if you're gonna use this for a Switch, I recommend using 2. To mount these, I used 3M double sided tape. For printing I didn't change any of the settings. Just opened it in my printing program, and printed.

Length: 3 Inches. Width: 1.5 Inches. Height of the tall back piece: 2 Inches. Height of the short front piece: 1.25 Inches.
