Complete mini 3D printer with Arduino core - Mini Replicator Prusa I3 based 3D printer
This contains all the files to print your own 3D Printer. You only have to buy the rest of the parts. Arduino or atmega 2560 R3, nema 17 steppers, end switches belts and pulley's and 6 mm axles and bearings and of course a hot-end J-head E3D a more precise list you can find on www.3dtje.nl  
In my opinion each 3D printer should be reproducing at least one sister or brother printer, in this case I developed a complete 3D printed printer.  
This printer is used in 3D printerworkshops at the Stockholms school of Economics and at the TKH stockholm (technical university)  
If you build this printer, please consider donating a second printer to a local school or a youngster who is really into 3d printing and technique. Let's put smiles on those faces ;-))
