Grippy Keychain Containers

I had some requests to make the exterior of the container more grippy since the knurling was mainly esthetic, and after some tinkering this is the result i came up with. (Exact same design but with a different exterior.) Feel free to give me feedback on how grippy it is when opening/closing, especially if you dont have a lot of grip strength or sensitive skin!

UPDATE 1.1: I changed the smaller lid so it has the same connection point as the large one (they seem to print better), i also changed the large container thread to the same type as the small container.

UPDATE 2.0: I changed the thread to a bigger one with a bigger pitch, reinforced the attachment point and altered the interior dimensions (threads, interior dimensions and attachment points are identical to my other keychain containers V2 models).
