Dice Box Mixer

This is the first model I've designed, I've only just recently (a couple of months ago) got my first 3D printer. I've decided to take up 3D modeling after many years (and a career change) and created this special box, to store your dice in, but also to be used as a dice roller, or dice randomizer during a game. This was initially planned to be used with a D&D dice set, but it can be used for any dice game.
This version is the second version of the box I've created (we'll call the first version a trial by fire to learn the 3D program - onShape, design process, tolerances, some mechanisms and more), and it allows for anyone to design a top part (called "cage") and I've released this model with a few different cages to print. Most of the objects were designed to be printed without support, but some must have them.
You can grab a copy of the project on onShape, if you want to print your own "Cage" for the box.
