What is internal diameter of PTFE isolator coupler for UM2+?


Recommended Posts

Posted · What is internal diameter of PTFE isolator coupler for UM2+?

I've been sent 2x isolator/couplers for 1.75mm filament.

What is the internal diameter of the UM2+ 3mm isolator/coupler hole so I can drill/rout the correct size hole?

Thank you!
