looking for air-tripper style mechanism

Hi all.
I can't print my own stuff yet so I was hoping to find a for-sale pre-built cold-end extruder:
...works on 3mm filament
...uses a MK8 hobb (or can adapt)
...airtripper-style adjustable pinching force
...uses direct-drive NEMA17 motor with 5mm shaft.
...all-metal design? not required, but I can dream!

I have the motor and the MK8 hobb, but I don't have time for the DIY (printed parts and HW).

A commercial model is what I am expecting to find.

thanks

Europe try Airtripper EU

USA Based try Airtripper USA

These guys may be able to help you out tho they both list 1.75 filament models.

For an all metal type see All metal Bowden extruder Kit Pricey but the metal parts are extremely well made.

Also look at Robotdigg For some very nice parts

You may want to look into the pro's and cons of the different sizes of filament with regard to direct bowden drive systems and the pressure/torque required to drive the filament?
