In 2014 I designed a folded metal 3D printer, and with collaboration with Waleed Kahn, we also designed a folded metal CNC machine
The designs have been sitting in Github since I closed the shop in Dec 2014, and it’s just sad to see two such really cool machine designs just sitting around.
So if you have (or have access to) a sheetmetal factory anywhere in the world, and you would like to sell these, you have my blessings and support! If you get rich off it, do remember to buy me some beer though! https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=45DXEXK9LJSWU
