Modeled as close to the in-game model as my Fusion 360 skills and patience will allow.
The top snaps on, to remove it you kind of have to squeeze the outer shell to pop it up, it's pretty secure.
The spoon was remixed from this model: https://www.printables.com/model/376354-pokemon-grenade-pokefrag/files
Printed with Bambu Labs PLA Silk filament: https://store.bambulab.com/products/pla-silk?variant=40802841395315
This model has been printed multiple times, but it is still a work in progress. Still working out the kinks with the copper core so it doesn't move around. I am considering magnets.
