Control box for CNC switches and voltage/current meter

thingiverse

I chose to create a control box that would house the main power switch for my CNC and also include a small automotive voltage and current meter. I wanted to add an automotive 24V to 12V regulator inside it, so I could use one power source to supply my 5W laser module, PC fan, and lights, as well as switching the power to my spindle motor. Therefore, I included switch cutouts for those components too. The design shown here is what I came up with. The main box body was printed on its side to reduce support material and improve print quality on a cheap 3D printer. The hole in the base was filled using two small screws that hold the small plate part in place. And, end bumpers were added to give it a bit of flair while raising the box off the work surface. It can be finished however you like, but I decided to paint it and add water-slide transfers before clear coating. I also chose to laser cut some 1.5mm mahogany sheet inserts for the bumpers, to make the ends look nicer. The files for the transfers and inserts are included here, as is the OpenSCAD file in case you'd like to make any adjustments or change the cutouts for a completely different use.
