What Our Customers Say

Verified
Hey, I have been "scared" to print the GF of CoexNylex filament for years due to the shear affect to the nozzles in question. But! Since I got the Ruby nozzle that recently became available for my K1C, I decided to try it out. I also got some hardened steel nozzles for testing the CF addition to the Coex Brand.
orders shipped quickly and the quality of the PETG is very good
