A while ago I downloaded some player material formatted and designed in the way of a sourcebook that included different class starports, flaws on used ships, and things like that. It was very helpful and like I said I downloaded it but apparently the download never stayed on my phone. Does anyone have a link or know what I'm talking about?

Sounds like Jaegergryta's

As Daeglan pointed out Jegergryte hosts some FFG fan made content on his blog. You may be thinking of Cartol's Emporium.

Both of those have good material but sadly not what I was looking for exactly. Hopefully someone remembers

LibrariaNPC's, maybe. The used ship rings a bell.

Maybe Nashable’s Starship Repair Rules? Or perhaps Starship Wear and Tear by Norsehound?

EDIT:

For the former, see https://community.fantasyflightgames.com/topic/133063-starship-repair-rules/?p=1421188

I’m still looking for links for the latter.

BUM BA DA DUM DUM DUM DDDDUUUUMMM

Bradknowles, you're a godsend.

Thank you everyone for helping!
