It is sized for 3/4″ plywood, but if you do cut it out, I would recommend starting with the cutting tool maybe 1mm off the surface so you don’t break through with your rough cut. I should have added tabs to it. Watch the circle cut outs as well, one my popped lose, so I paused the print and pulled the piece out so the finish passes wouldn’t hit it and break the tool. The program is written for 1/8″ cutting tool.
My finish passes in that code don’t take much off, but its still fun to watch it work! Hope my zip file works for you.
