About this model
I was having some issues with filament getting soft and wrapping around the bondtech gears in my MK3. This was particularly bad for flexible filaments which require major slowdowns in print time. The issue is there is a tiny gap between the hotend ptfe tube and the bondtech gears. There's two ways to fix this issue: 1. Put a slightly longer ptfe tube in the hotend that extends up to the bondtech gears. 2. Reduce the gap with a small 'cap' in the extruder casing that extends up to and around the bondtech gears.
