This is just a simple toggle switch panel for the Ikea Lack Enclosure. It will accommodate any toggle switch with a M12 bushing size. I used a NKK S1F, Part #: 360-1887-ND for example.

The screw holes are M4 size.

I printed mine in PETG at 0.2 mm with a 50% infill, but it should print in other filaments just fine with small tweaks.
