Ender 3 (Pro) Rocker Switch Bracket
thingiverse
I liked Schtimpy's idea of tucking a rocker switch under the control panel in https://www.thingiverse.com/thing:3364136, but my rocker switches were somewhat bigger. This sits behind the front of the control panel, held in place with the existing bolts, with the switch held tight against the panel. I suggest first rotating the piece to lie flat on its front face, and printing with supports to hold up the back. The switch I used: https://www.amazon.co.uk/gp/product/B073PC3K9Q Switch mount dimensions: 28.3mm * 11 mm.
