Beautiful Gray

Had some with this filament. It flowed beautifully and I think the little truck turned out great for this somewhat complicated print. I’ve been using Proto Pasta for I believe around 9 years, never disappointed. Printer - Ender 5

Thanks Derek

Excellent print quality with my LDO trident printer. It's a nice no-nonsense grey that is very versatile.

Protopasta never disappoints

I've used Protopasta's plain PLA before and found it to be excellent filament - clean, no hassle prints with excellent appearance. On my last purchase I needed a gray color and decided to try their HTPLA. I was not disappointed at all. Same color quality and print characteristics as their PLA. You really can't go wrong with Protopasta.
