Minimalistic MK7 with Cleaning Brush
thingiverse
Whosawhatsis created a Minimalistic MK7 version based on a design found at http://www.thingiverse.com/thing:15718. To enhance functionality, this user added an 8mm hole for inserting a cleaning brush that automatically cleans the extruder pulley. Additional updates include a bottom cutout for a stepper motor and modifications made on March 28th and 29th. The model features a 50% infill with 2 layers, utilizing springs from Ikea clothes hanger clips and small bearings with an inner diameter of an M3 screw (possibly sourced from an old hard disk).
