The last couple of weeks I've been building a 3D printer in order to build cases and frames for my PCB. It's coming along really nicely so soon I can start printing frames.
It's an MendelMax 1.5 printer with an QU-BD extruder. Some modifications have been made to the extruder because the original tensioner for the filament was really bad, it had no margin for error in the filament. We made it spring loaded plus a bearing to make it slide better and with less resistance.
