This is a box for a toggle switch intended to be attached to any printer with 2020/2040 aluminum profiles. The internal dimensions of the box are 41mm (L) x 28mm (W) x 34mm (H). The hole through which the toggle switch goes through has a diameter of 0.5 inches (12.7mm). I have also included a cutout on the back of the box- when mounted, this allows wires hidden within the aluminum channel to enter into / exit out of the box to maintain a cleaner look. The lid is a snap on lid.

For reference, I am using these toggle switches: https://www.amazon.com/gp/product/B01KSMNUGA
