Home of Piper 3D printers
Currently, we have 2 models of 3D printers Piper 1 and Piper 2 both are available for the public under CC license .
It may have a bed size as small as 100×100 mm and as large as 500x500mm. Its linear motion system is built on cheap 1/2 inch conduit pipes, which cost 3$ 10ft in the US. So if you want to expand your printer’s bed – spend 3$ more and cut new sizes (do not forget that you will need new belts as well).
