Filament tube


Do you have any reference or size for the transparent plastic tube in which the filament is guided to the extruder ?


Best regards

diameters: 3mm inner, 4mm outer 

edit: my bad

diameters: 2mm inner, 4mm outer 

I'm measuring 3mm ID, 4mm OD?  2mm only leaves 0.25mm clearance in the tube from filament.

Yea, mine are 3mmID x 4mmOD


I ordered both size (id 2 and 3 mm), just before Marcin corrected his post.
