Minimalistic MK7 with Cleaning Brush
by benmah, published
I have made this Minilistic MK7 derived from http://www.thingiverse.com/thing:15718.
I felt that I need to have a cleaning brush inserted to automatically clean the extruder pulley.
8mm hole for brush
Bottom cut out for stepper motor.
Thanks to whosawhatsis for this spring version of Minimalistic MK7.
Print using 50% infill, 2 layers.
Spring is from Ikea clothes hanger clips
Small bearing with inner diameter of an M3 screw.(From my junk box which I think from a old hard disk) Will update the bearing model number later if I can see the imprint.
