On this page, I share my thoughts and provide links to various filaments I use.
The baseline and bare minimum: dirt cheap and accessible
eSun's PLA+ is one of the best values in filament. It is inexpensive, consistent, and easy to use. Meant to be a sturdier version of PLA, eSun puts durability within reach for much of the home gunsmithing audience.
Just like PLA though, don't leave it in direct sunlight.
Live next to a Micro Center? Inland branded PLA+ is the exact same as eSun's! It's just whitelabel. You'll save a few bucks getting it in-person too.
Vinh's Thoughts: This is the baseline filament I recommend to *everyone*. It's cheap, and it's durable, with no-frills.

PolyMaker PolyMax PLA (formerly "Tough PLA")
The upper height of PLA durability
Pricy, but it's worth it. This I would say is the most durable (and high-quality) filament you can buy for PLA+.
Vinh's Thoughts: PolyMax is what I print in when I have a model that I know won't need further printing or revisions.
