With the arrival of the Core One I had some difficulty reaching the power switch in the back of either the XL or Core One. I made this box to house two remote switches I bought from Amazon (link below). It uses 4 M4 nuts & bolts to secure the switches and has 4 holes to mount to a wall. The cover is a press fit. Additionally there are covers for the bottom holes where the cables go through. They are not the best design but I don't think they need to be very robust. Just good enough to cover up the gaps. The wording is on the cover and you can paint it in the slicer. I used Hilbert curve for the visible layer and I like how it turned out. The .3mf file for the XL 5T is added for the cover already painted with Black, Orange, White as 1-3.
