thingiverse
Adapter to use a 7mm diameter pulley on an MK8 aluminum direct drive extruder. Tested with 1.75mm filament. Reducing the filament pulley diameter from 11mm to 7mm allows motors with less torque to be used. There are two versions: open and closed, with the closed version having a more restricted filament path. Extra parts needed: - A 7mm diameter filament pulley - One 624ZZ bearing - One M4x8mm flat head screw - Two M4 nuts See it in action here: https://youtu.be/Yt0ruqpbm2U If you're a curious maker, tinkerer, or hacker, check out my blog at http://www.therandomlab.com
