3mm and 1.75mm 3D printers are incompatible - but it’s pretty easy to convert to the more modern 1.75mm standard!

Would be cool if E3D or someone else offered some sort of universal way to use both filament types. That would have to include extruder mechanism though. Closest I can think is the Ultimaker which uses a 3mm bowden tube, but you can get a specific size 3mm od, 2mm ID PTFE tube to throw in there, in order to convert to 1.75mm “on the fly” so to speak.

I wonder if a in-line heated reducer could be made 3mm on one side pulled through a heated tip to 1.75.

For the super soft flexible filaments (e.g. Filaflex), 3mm is still the way to go for reliable fast printing.

@Ross_Bagley you may find my article useful with some tips on printing with flexible filament : http://www.gyrobot.co.uk/blog/how-to-3d-print-with-flexible-filaments

Anyone know where I can get the files for that gregs?
