Description

This is remix from Minimalistic Mk7 replacement
http://www.thingiverse.com/thing:15718


Advantage of this mod:
1. Quick release/loading of filament, by pressing the lever to disengage the drive gear.

2. Allow easy cleaning of drive gear (it is exposed). You can clean it even during mid-print.

3. Smoother feed than the stock zen drive.


Even though it will provide smooth filament feed, I don't think it will solve all your filament jam problem. For that, you need to look into your hotend.

Should work with both the old & new drive gear.
