This video is about making cubes on the Shapeoko CNC. I have made a zip archive of the cut out files along with 3 of the side patterns I use (including the one in this video). These side patterns are all open source or my own designs.

The symbol on the side is from a package of screens available here: https://www.cncfiles.org/filebase/file/110-seperator-patters-raumtrenner
