This storage container is an Illuminati Eye of Providence pyramid based on the one seen on the U.S. dollar bill. The idea is from littleTup's pyramid design found here: https://www.thingiverse.com/thing:3653612 which is a great design. In fact, I was going to print this one, but then decided I wanted to make it more like the pyramid found on the dollar bill. Then I came across FiveNights's model for the mini Lamp which is also a great model. Basically, I took FiveNight's model, hollowed it out and turned it into separate compartments in the same way that littleTup's design works and then added PlasticDesign's version of the eye. The secret compartment cover lid is pretty thin and hard to print.

You only need supports for the lips that hang on top of the compartment below it. Also, make sure you have good bed adhesion. The base is 140mm x 140mm. If you have a heated bed you should be okay. I don't, but I print on glass and hairspray usually works great. However, I don't normally print objects all the way to the far corners of the bed, which I think didn't get covered as well by the hairspray so I had a little warpage on some of the corners. You can use Tinkercad to add a special message on the inside if you want to make it a gift.
