My intent with this was not to make a frame that can replace the kitbot as being easy to assemble with so few resources, but to create more of a library of designs for teams with limited machining and mentor resources. S_forbes posted a design that is very similar to one I was working on
here. The materials are readily available, it requires very little machining (biggest task is drilling the bearing holes, which can be doen with a forsner bit on a drill press), and is inexpensive.
