No one had a control panel that I wanted or fit my design needs for my filament extruder, so I made one. This control panel will support up to 3 slim switches and 1 larger switch, for a total of 4. The switch holes are covered but you notch as many as you need. They are designed so that you don't have holes all over your control panel. Below is a list of products that fit this print.

Large Switch
It's a Servalite LTGC501U, for some odd reason I cannot find the link for it on Lowes website. It's there and they have them.
