This is a good printable box with two lid options:

Slot lid - great for notes, cards, etc...
Closed lid - to keep secure inside

• You can scale it to any size you want
• Easy to print, no supports needed
• Both lids fit the box perfecly

Make sure to scale the box and the lid by the same percentage so they fit perfectly together.

Feel free to like or share a photo if you print it ! :-)
