Frequently asked questions
Which filament types does this pipe support?
The listing states it is suitable for 1.75 mm ABS and 1.75 mm PLA filament.
Will 1.75 mm filament fit through the 2 mm inner diameter?
Yes. The 2 mm inner diameter is larger than the 1.75 mm filament, so the filament passes through with some clearance.
