Some renderings I did of Solidworks models I did awhile back. I was toying around with the idea of an openbuilds slot modular system design. Came up with a little mini CNC design and a big brute of a cNC machine. Polar opposites. Cost of building either these two would be too much for me at the moment. The openbuilds system gives you the possibility to build all sorts of things like 3d printers, mill machines, anything requiring linear motion.
