Where to craft ultra glide fins?

[HellSlayer]

Maybe the title is a bit spoiler'ish but.. I have ultra glide fins in blueprints.
I have all the resources for it including aditional fins. And I cant find where to craft it.

Am I dumb or just overlooking something? thanks

It's an understandable confusion, though not as common as the sudden swerve of not being allowed to make your vehicle upgrades at the vehichle upgrade station when trying to get bigger depth modules.

You gotta use the Modification Station for specialty fins.

I've been playing so long my eyes glaze over it, but does the PDA still have an inconsistent naming scheme? EDIT: Ah, they finally call it Modification Station in the blueprints, instead of something else. So that's one less point of confusion newbies will have to worry about these days.

I havent found any workbench or modification station.
I do have locked multipurpose room because I havent found the parts. And maybe thats it. Anything else is doesnt ring a bell. Havent unlocked seamoth or cyclops yet. Only scanner room which is very helpful.

I do need to find the laser knife since that would allow me to scavenge some unreachable areas.

Good to know Im on the right track.
