thingiverse

This mini printer is made out of Sweeper (Swiffer brand). So I have named it Swifty. Body frame is stick from Swiffer. and others are printed parts. At the beginning, I tried to use old stepper motor from paper printer, smooth rods, desktop switches, bearings from printer parts and timing belts from recycle purpose. But later there was quality issue, so I realized better to buy proper parts specialized to cnc machines. Build size: 100x120x80 (xyz) Required materials are below.
