Hey guys, I looking for a new PTFE guide tube that would be good

Hey guys, I looking for a new PTFE guide tube that would be good for a 3mm filament. Any recommendations?

I’m currently using an ID: 3mm, OD: 5mm tube but I can’t seem to feed any filament through it. Are these the right dimensions for a tube or should should I be looking for something else. Thanks!

1/8"ID, with 1/4" or 3/16" OD. 1/8" is 3.175mm.

I had the same problem trying to get 2.9 mm filament down 5 mm od tube. In the end l ordered some from E3D. It works fine and is 6.4 mm od and about 3.4 id.

At E3D we ship exactly what @Whosa_whatsis says, has just the right amount of clearance while still constraining things properly.

@Sanjay_Mortimer Would you mind sending a link to E3D’s site?

We mainly do hotends, but also sell a whole bunch of useful printer stuff, including the tubing by the 100mm.
