Experimental Rostock extruder

Experimental yet fully working direct drive extruder for Rostock delta printer without Bowden tube. The design was made for easy conversion of Airtrippers Bowden extruder and uses almost the same parts. The parts required are a Nema 17 motor with mk7 drive gear, a 608zz bearing and a couple of m3 screws.

This extruder adds a lot of weight and can only be used at low print speeds. It decreases the print height with 61mm plus the length of the hot end.
