Heinrich Schlechter is a South African software developer who built this “cheap, quick and very 'hackable' bootstrap printer loosely based on the RepRap 'Adapto' machine he calls the Ad(str)apto. It features a build volume of 200 x 200 x 200 mm, and you can build the entire device with easy to find parts and common hand tools.
