Bowden Tube

[MTG 8]

Hey,

for my modification I need an bowden tube thats a bit longer than the stock one. When I'm searching for PTFE tube, I can't find Tube with inner diameter 3mm / outter diameter 6mm.

Most of the tubes have 4mm on the inside when outter diameter = 6mm. Does anyone know where I can buy that tube so that I cant cut my own length from it?

I am not sure, but I think I have seen Bowden tubes at the Bondtech shop where you can order per cm or so.

...in addition: Ultimaker printers do not use bowden tubes with metric dimensions (AFAIK).

You probably want one with 1/4 inch outside and 1/8 inch inside diameter.

Where are you located? Here's another example in USA: https://www.captubes.com/

Yeah I just had this Idea too. The one I ordered from Amazon is 4mm inner diameter, 6mm outer diameter and it works quite good. Maybe I would have trouble with flexible filament...

 

I'm located in Germany. On  German Amazon I can't find any inch-tubes. US shops seem to have very high shipping costs for just a tube worth 20 bucks

 

Edit: Just noticed that my tube does not work. Outer diameter is too small so it pulled itself out of the holder...
