Introduction
Replacement Filament guides for E3D Titan.
I was having problems printing flexible filaments, with the filament getting squeezed past the hob gear and bunching up. This was caused by the excessive clearance between the injection molded PTFE guide and the gear. The stock components have a 0.4mm gap between the guide and the hobbed gear. This is 25% of the filament's thickness and easily enough space for the filament to be forced through (when that filament is NinjaFlex!)
I have designed these guides to reduce that clearance down to almost zero and to bring the PTFE tube right up to the gear.
So far this has done the trick, but I will keep you updated with any new developments (see updates).
Printing
The part is available with a 4.1, 4.2 and 4.3mm hole in the middle, so you can choose the one which prints best on your printer to fit your PTFE tube (4.2 was best on mine).
I printed them at 0.1mm layer height on my modified CR-10
Update 1:
This part does a great job of constraining the filament as it…
