Really Tiny Printable Extrusion

THIS...this.. is a very cheap to print and use 3d extrusion, while being surprisingly strong even in pla. It's designed for 2mm screws which are incredibly cheap from china on ebay. I was making and printing huge monolithic computer cases and parts, and when a print went awry I threw out a huge hunk of plastic because one edge was missing or something. After a shamefully long time, I figured out I should make computer cases the way I make 3d printers. The large flat pieces are easy to print and these are easy to print and melt together with a soldering iron, if you can't just link them together with some "I" plates. A few cheap bolts, and I can make any crazy computer case I feel like
