SV06 PTFE filament guide

SV06 filament guide

This filament guide tightly constrains the filament using a Bowden tube. 

Compared to other filament guides with a wider space, this design further prevents the filament from curling around, which is especially likely when your spool is almost finished. 

Material:

you'll need a small section of PEFT tube (OD4mm, ID2mm) and a PC4-M6 coupler. 

The whole thing gets clamped under the original spool holder so no additional hardware is required.

Instructions:

to assemble the PTFE coupler, simply thread in the hole. The direction doesn't really matter.

To fix it to the printer, unscrew the two M5 bolts on top of the printer that hold the spool holder until you can slide the filament guide underneath the metal bracket. No need to completely unscrew the bolts.
