Children stole my Easter eggs last year. But this time, I'm ready to face them with my safe deposit Eggbox.
This is a design I printed only once for fun. It is of course not perfect, and has a lot of flaws ; closes not so well, can be opened easily without being a experimented thief (my young boy opened it with a wood stick), can be smashed to the ground, burnt, cut...
Main part with key hole must be printed head down WITHOUT supports.
Once printed, turn the lock gently to detach the undesirable strings from the internal gearing.
You can add some grease inside with a small brush.
The shell might be printed head up with supports for good results.
Tighten the 3 parts of the shell with M3x8mm or 10mm screws.
I hope this will help you to spend Easter holidays safely !
