[US + Worldwide] Complete Airtripper BSP BOWDEN Extruders

I'm selling several complete (motors included) Airtripper BSP Bowden Extruders. I converted my printer to a Bowden setup with the wonderful E3D hot end, and it worked great. Good hardware was a pain to source; hence, I decided to offer several of these for sale and hopefully benefit the community. I've been using mine to print at 120mm/s with large 3mm retractions (80mm/s filament retraction speed). I've seen no slipping and no stalling since I started using this kind of motor.

- Extra-long, high torque NEMA 17 motor (70oz-in or 50 N-cm)
- MK7 drive gear as recommended by Airtripper
- Completely assembled and holes cleaned up with a drill
- All the bearings, machine screws, and the hard-to-find 1/8" 4mm push fitting
- Spring tensioner instead of rubber tubing

Right now, I have several in blue and one in white. PM me if you're interested. The price is $70 with free shipping in the US. If you're outside the US, please contact me for rates.
