I tried this on my Kossel Mini. I have a MK7 gear, and it just did not have enough torque with a regular NEMA 17 to drive 3mm filament bowden style reliably. The slightest back-pressure and it was stripping out filament. I really like this simple design, and wish I could have made it work! Bravo on the good design and support of this thing.
