    Hi,

    Just got my Robo 3D Plus and I mainly need to print in TPU. I got the mod for it, but I cannot find where I can get the PTFE tube?

    Does anyone know the OD i need to get? And if there is a local store I could pick it up so I dont have to wait? Lowes and Home Depot carry sizes but they are too large.

    Lastly, anyone have a picture of the tube installed? Or advice on exactly how to put it in?

    Thanks!

    I bought mine on amazon. 2mm id 4 mm od. I think the thread @mark tomlinson has for you might have the link to it. I didnt have any luck at a local store but it would be worth a look.

    The first tube I used was (seriously!) a small plastic tube from an R/C hobby shop. Gas line I would guess.
    I just had it laying around and it fit :)

    I later replaced it with 2mm/4mm PTFE and that is what I used on the second one as well.

    Ptfe tube here as well. I think its one of those things you need a tube... but any number of them may or may not work for you. Going to have to play with it and see what works best for your set up

    Honestly you can get away with the inside of a pen with the ink removed. You just gotta find the right size.
