Traveling with a fragile 3D printer can be tricky. MakerBot Industries recommends Pelican cases for their printers, which are pretty much rectangular. However, the RepRap Prusa’s shape is much odder, inducing Thingiverse user crankbmx to build a form-fitting case that even has room for the spool, and can print while... Read more »
