It's very good for entertainment  and you can't use it for high quality .

J. Prusa really built an incredible machine.

This printer needs no comment. It's incredible, remember? But to achieve this, it needs to be calibrated like a boss. Be in mind that piece of paper put between the nozzle and the bed it is just a last check when the printer is already FULL calibrated. Only noobies believe that a single paper make miracles. If it wsa a Graber i3, the work/fun will be bigger. Print new X axe supports (motor and idle)and throw away the old plywood ones. Change the ordinary 5mm threaded bars of Z axe to 8mm trapezoid threaded bars. These printers can print high quality pieces, believe it.
