For gifts or just storing your secrets in, this rocket ship puzzle box stands nearly 12inches when fully assembled, the inside is roughly 3x 6 in its cargo bay lol.its pretty simple to print and the puzzle can be solved relatively easily.the main body, window, and cap need to be glued together, but before you do, consider putting a bell in there. This way the storage box can have an alarm when someone tries to tamper with the stash.

Update Dec 30, I have revised the fit between the main body and the maze to be a little tighter as it seemed loose. Added a coin Bank Option for the top cap and the main body if you want to make a coin bank out of it.
