This model is a small control box/switch housing for an Ikea Lack enclosure. It's made for pretty common switches with about 12 x 26mm cutouts and an additional notch for its locking mechanism. The box is fixed with four small screws. They are a bit difficult to fasten as I didn't design a cutout on the opposite side for better stability.

You can print the box using a single color or choose a different color for the icons. I've already attached a prusaslicer project and GCODE for a poor man's MMU. I've also attached the openSCAD file, so you can modify them as you want.

It's designed for a layer height of 0.2mm, material and infill density doesn't matter that much.
