This is an under desk controller holder with switchable plates. This mounts underneath your desk using a #8 screw. It also has a hole to fit the chord if you've got a chorded controller, or for charging.

If you don't want to swap out plates then you can print the Mario star one which doesnt have swappable plates “Under desk controller holder Star”.

If you want to be able to swap different plates with icons you can print the plates, and the "Under desk controller holder with slip panel".
Plates are slid into the holders from the side.

There are two types of plates:
-One that has a pause already set in the 3mf file to manually swap colors.
-Then one single color one, that can just be printed single color if you don't want to swap colors manually.

When printing the custom plates dimensional accuracy will play a part, Depending on your printer and filament the sizes may vary slightly, minor trimming of the plate may be necessary.
