E3D direct geared extruder mount
It takes time to design and create these things, so if you like it.... the "like" button is not that far away from the download button to show some appreciation ;)
For the new Cyrus 3d printer I am going to use the E3D extruder with an geared motor. currently in early phase of testing , I Haven't printed anything with it yet but I don't forsee any problems with it.
I would do at least 50% infill, I did 75% for my own. only 3 pieces to print. Pressure is adjusted by simple screw (see cross section render).
It is currently in working condition :) tested it myself today work's great
