by Printing-3D, published
Printed in ABS and bottom plate and motor ring glued together.
Spring, MK7 drive gear and 608ZZ bearing used to get the correct pressure on the filament. First tests with 1.75mm filament gives excellent grip.
Next step is duration testing. Keep you updated
Printed with ABS fill grade 0.9. Drawings made within sketchup, used slic3r to generate GCode. Used my Creatr printer to print the parts.
