Added a few variants on the base including a wall to stop the dice rolling under the stairs and a longer (20mm) version of the base so that there's a bit more room inside the box.

I've uploaded an STL and STP file of a blank lid incase anyone wants to get creative and add their own patterns.

So this is my latest 3D printed dice box/ tower design. The box itself is 110x120x30mm so relatively compact but plenty big enough to fit the dice tower mechanism and a full set off dice (maybe even a miniature if the base isn’t bigger than 25mm square). The dice tower itself stands at 100mm tall and is made up of 20 individual step pieces that rotate around a centre spindle. The design is purely 3D printed with no need to glue any components together (although some of the retaining pins would benefit from a bit of glue). The push-fit tolerances are all a little tight, so it took some sanding to get everything sliding and spinning correctly.
