10mm PTFE Bowden Coupler Knob

To go along with the chunky feeder knob for the extruder https://www.thingiverse.com/thing:3567656


Here is a small one that slips over an aftermarket 10mm PTFE/Bowden coupler (rather than the standard 8mm the printer comes with)

Not really needed but looks nifty.


there should be plenty of clearance if you are using an aftermarket mk8 extruder with screws holding the spring.


print at 0,2mm and rotate so the stem is pointed up.

If it's too tight/small either lower your flow
