Freminet Diving Backpack from Genshin Impact.
This model is entirely made by me and it's based on my personal interpretation of in-game images so it isn't the original model of the game.
I'm planning to update this design with a sliced version of it for make it easier to 3D print it, at the moment it's only one single solid object.
If you need some help in slice it for 3D printing don't esitate to DM me.
