This is an improved version of the dice tower made by JonesSepp.  https://www.printables.com/model/74357-dice-tower

The changes I have made are reinforced arms on the cases and I made a cut away in the base of the Tower to allow the cases thicker arms to still open completely.

The tower and the two cases are both easy to print. I used PLA with a layer height of 0.2mm on a 0.4mm nozzle.

I was able to print all parts without support using Ultimaker Cura.  I copied the portion below from JonesSepp Description since it is still applicable.

Both cases have holes for the screws. They are a bit wider so M3 screws just fit through it. No support is required.

Additionally, you need to 4x M3x10 screws and 4x M3 nylon nuts. And 2 dices as well!

I printed all of this on a Creality Ender 3 V2 NEO.
