There is a twin model that does not have a hidden compartment: https://www.printables.com/model/989143-david
You will need to add supports on the head. I let PrusaSlicer figure out where they needed to be and used organic type supports. No supports are needed inside the secret compartment (even if your slicer tells you otherwise).
I hope you like ❤ this model and will post your makes!
Happy Printing!
The author remixed this model.
I cut the model into two parts: the head and the base. Then I cut into the head from the bottom of the neck to make a secret hidden compartment. The base has a threaded cylinder that screws into the head. When assembled it looks similar to the original.
The compartment is spacious: 35mm diameter x 90mm deep!
