UM2 part for original feeder for flexible filament

[glloq 0]

hi,

I just published a modification of the original feeder UM2 to use flexible filament.

The explanation is in French, but it is so simple that the pictures explain everything.

With the filament Taulman Bridge or PA6 filament work any good.

I have not tested the NijaFlex.

if you try to put a flexible filament in an original UM2 feeder, you will see that the filament passes behind the wheel of the feeder, because there is no guide.

The flexible filament always escapes by this empty gap.

This part prevents this, and the filament stays in a good position.

It will solve cases where the filament move out of the grip (to the rear) of the feeder wheel and bearing. It wont solve the case where the filament is so flexible and sticky that it bend between the feeder wheel and the entry of the bowden tube.
