DetailsConvert to 1.75mm! This is experimental. I haven't tried it - I don't know if anyone has. I'm not sure if changing this part alone is enough - it seems like it should be as on the UM2 you only have to change the heating block and the teflon part - certainly you don't need to change the bowden. So I think it will work.
Replaces Ultimaker Original (not Ultimaker2) teflon part but this part can print at 255C continuous for years. Never replace your teflon part again. This is made of teflon but it's a high temperature teflon.
