Designed for a 4x4 CNC to be cut out on a 4x4 CNC. Plenty of holes to run cables and cords. Four drawers for all your tools and bits. I'm going to make a version you can build with OSB, it'll be cheaper to make, but will likely kill a bit in the process. OSB is mostly glue and kills bits after a few sheets. Assemble your machine on the floor and then start feeding in sheets. Files are available for both 12mm and 7/16.
