Worked As Expected

Had the fitting go on a bowden extruder and was shocked to see it wasn't the M6 version. This did the trick and is holding the tube very well.

Great quality and build.

I've been using this in a dry filament box. No problems so far. If anything, it's fixed all the problems I was having with feeding the filament to the printer. amazing!

Good quality

Perfect for bowden tubing on a 3D printer, I bought this and the M6 version for a new build printer, ended up fitting perfectly.
