For various small Dremel and Proxxon tools, we needed a box to keep it. So this is a gcode-only-example done at the cologne fablab "dingfabrik.de". One DIN-A4 size 4mm plywood is cutted by the CNC-mill into 4 layers. Use a 3mm tool for drilling and cutting wood.The 3 bottom layers need to be glued to the basic box.A 12mm long M3 screw holds the top layer together with the basic box. Slide it to the top to open the box.Finish.For spheric tools, I just drilled a larger fitting into the box, so I needed no further changes at the gcode.
