MiniExtruder for Prusa i3 (mini) and RepRapPro hot end

I have tried to make a MiniExtruder-drive for RepRapPro-hotends fit to a standard Prusa i3 / i3 mini printer (I want to have a i3 mini in the near future). First tests looked good - let's see what the real printing jobs will look like.

The extruder has mounting holes for 24mm and 30mm mountings with M3-bolts. As my MiniExtruder this one also works with a Nema14 stepper motor.

Need a matching hobbed bolt? Write a pm or an e-mail (3d.andy(AT)gmx.net).

I have uploaded two stl-files:
