I absolutely LOVE my Class 4 CO2 Laser cutter/engraver. But it definitely needs some improvements. I’ve added custom lighting, camera, and analog milliamp reader to it and needed a control panel to manage everything. I designed this as an inset panel that controls the AC lines (which are connected to a new UPS).
My 3d printer always prints a little larger. My designs need about 0.5-1mm tolerance for fittings so I printed out this flat plate to test the panel mounted switches and hole placements.
