One of my favorites

One of my favorite colors to print! The deep gray tone is subtle but I can't recommend it enough!

Oh, my!

I just got the best 3DBenchy I've ever had using this filament (and I've been printing them for years). Not only did it print beautifully, but the glitter effect really hides the layer lines. More when viewed with the naked eye than in these pics. I'm printing on a Craftbot Flow IDEX that I've been using for a few weeks now, and it's as though the printer just got an upgrade.

So good

Love this stuff. Haven’t tried the HT portion of it yet but I really like the look and the pint ability. This was my first purchase and I’m now hooked for life on pasta.
