Here's the STL for the zyn lid and base. Fair warning, the gunmetal edges in the cap were difficult to print with my PLA. I only tried once and they needed a good bit of sanding. This may be prevented with a finer resolution nozzle, but I'm no expert. Either way, it'll still turn heads.

I also added a USMC crest engraved lid I made for a friend that I might as well put out there for more people if you can relate in any way. He mentioned he printed a gasket out of TPU that made it safe underwater!

Hope you enjoy it!

Don't feel like you have to but if you want to buy me a zyn, that would be much appreciated!
