Summary Customizable blocks with customizable holes. The idea here is that you make your own building system for making re-configurable CNC, other multi-axis bots, and anything else you can dream up. The sample files are based on even 1/2 inch increments with 1/4 inch holes. (To fit with common items like pegboard, perforated angle iron, 80/20 Ready Tube and even steel plumbers' tape!) NOTE: Some of the parts in the concept drawing are generated from other derived tools which will be uploaded as soon as they are ready. Custom Section TODO Thread the edge holes and make the sides into through holes, similar to: https://8020.net/university-readytube
