I've decided to sell my Qidi Tech-One 3D printer. This is a Makerbot Replicator 2X clone, with dual extruders and a heated bed. It is an amazing machine and has been incredibly reliable. It is currently set up to print ABS but I've had great luck with PETG, TPU and PLA filament in it too. It is in excellent working condition. Comes with a nearly full spool of black ABS filament loaded into the left extruder.
If you're interested, email me and I'll set something up. I can put together a small demo-file if you want to see it print in person.
