Polydryer PTFE 0.4 Stopper

I needed something to allow me to use the more common size PTFE tube (OD 0.4 mm) and not have the tube pushed into the Polydryer. I was not ready to swap for a push to fit coupler yet. Also wanted something I could add to it after I fed the mile of filament through to the MMU3. Quick and simple to print and use.

No need to re-feed filament through.

I used .2 layer height to print. Does not matter infiltration, unless you only use 1 perimeter. No supports needed. But make sure good bed adhesion. Had first one get loose.

Open to suggestions for changes.

12mm height / 8mm to lower lip

7.6mm outer diameter / 4.2mm inner diameter / 2mm filament opening
