Locking Container - Key needed to release thread!

I needed a simple container to store some USB drives. This snowballed into a 'hidden in plain sight' threaded container that requires a key to access the contents! Multiple sizes available which will fit a variety of items you may want to keep locked away. Chocolate, cash, Crypto wallets, cards, candy, AirTags, jewelery, medication, USB's, etc, etc! I've tried to design this in a way that the container doesn't look out of place as a decoration. You can be the judge of that! The Key is common across all container sizes. There is a spot on the key for a 6mm x 3mm magnet, dab of superglue recommended. The magnet is purely optional and doesn't affect the container locking/unlocking. The thread has been intentionally designed to be a tight fit to prevent someone unlocking it with their fingers! Large Container dimensions: 125mm x 75mmMedium Container dimensions: 85mm x 62mmSmall Container dimensions: 45mm x 50mm In theory, scaling parts in the slicer should be possib
