GreenGate3D LOVES to partner with industry leaders.  Slice Engineering, Billie Ruben, and now Devin Montes!

Devin’s cool inspiration has touched millions of people, encouraging them to be a creative problem solver and not just accept the world for what it is.  His resolve to improve and construct a solution – make an impact – is what drew us to him.  We’re all not engineers or designers, but there IS a maker in ALL of us.

Together, we present to you, Devin Montes Cool Grey!

Cool Grey has a slight translucency to it… almost wax-like appearance… enabling the maker to find that mark between opaque and translucent.  Print it thick and get that dimensional look, or print it thin and you’ll catch some nice light.

Stay Inspired!!!

Prints like butter.

This stuff prints so smooth and easy it’s hard to think of going back to pla. This has a very wide/forgiving temperature range which on a tower for me looked really good from 225 up to about 260! (unlike most other filament that might have a range of 10-15° or so).
This is really great filament that doesn’t have to cross an ocean to get to you, is made with recycled pet by good people, running a family business. I can’t find many other reasons to recommend buying a thing or supporting a company than those.
The color is similar to the Prusament Grey with slightly better shine and print characteristics. As with all other petg, it’s best to give it a few hours in the dehydrator but I decided to try a spool right outbid the bag and it printed well (though there was modest improvement over its already pretty damn good print quality after drying and printing another project a few days later)

Might just become my go to grey!

Overall good experience with this cool grey PET-G. So far I've used it to print a handful of bag clips and just finished a Lion "Mythic Mug" soda can holder. Still need to fine tune my settings , but beyond that I'm just looking forward to what I can print with it next. (Oh! And the little surprise rattling in the box was a nice touch 🍬)

What! recycled plastics PETG!

This GreenGate3d PETG is awesome. I have used several brands of PETG with different degrees of success most was a waste of money. The cool gray is by far my favorite color but besides that this filament just prints beautifully and is smooth as silk. No buggers or globs smooth layer lines Too! My go to for PETG is GreenGate3D. Oh! they sent a sample of their green PETG its my favorite color too! Try GreenGate3d you wont be disappointed.

Great filament!

This filament is amazing. It came in the mail today and I’m happy I got it in 3 days total from order to delivered. In the box, I was greeted with a cool pen/touchscreen pen. Also some starbursts. Can’t wait to print with it. Definitely worth it to buy!
