I’ve made several boxes where I set up the MPCNC to route the top and bottom out of the same piece of stock. The lid then fits over a raised rim on the bottom to form a box about 1.35" tall with a cavity just enough for some jewelry or trinkets (about 1.1"). This time I tried a two sided operation with an engraved face, just flipping the stock and re-zeroing at the corner (bottom right for the engraving, bottom left for routing). The setup in Fusion 360 was not hard, but needed care to get exactly right since I didn’t reference with pins, but it came out quite nice. I left .015" gap for clearance on the lid and did 2 finishing passes with a .010 stepover to get the lid to fit nearly perfectly. Then just sand the sides flat to remove tabs, spray the top with paint, plane off with a sharp plane (see Rob Cosman’s tips on sharpening) and a final finish with some lacquer. Took 2.5 hours for each box. Happy to share the Fusion design if anyone wants to try it out.
