I took the awesome mewtwo model that https://makerworld.com/en/@alessandro.zama made and I cut it up in bambu slicer until I got just the head. I then put it into blender added eyes because the head model I had didnt have eyes. (the eyes were in a separate file) I then remeshed the head. Then I scaled it up to hold a full commander deck for MTG. I then exported it as an stl and moved it into Fusion360 where I created dimensionally accurate stls to add in the deck box cavity and the sliding lid. Moved all of that back into blender and cut up the mewtwo head.
My son requested a mewtwo head to hold his pokemon cards. So I found this model that looked like a great mewtwo and added cuts and a cavity in it to hold cards. I made it so it will hold 100 double sleeved cards in case anyone wanted to print this for an MTG deckbox rather than just for pokemon cards. My kid loves it and I'm looking to do Eevee and Pikachu for my nieces. Let me know what you think. There are some supports needed for the bottom of the head around the mouth.
