Bloodbowl dice tower

I took this one:

and played in tinkercad to add the spiralling extracted from this dice tower:

the 4 little holes in cover/tower are meant to be fitted with 3x2 mm NdFeB magnets
the cover may be filled with dices, and then snapped on top of the tower, so the dice will flow and exit!

I still have to print so if you try before me, please share if you encounter any problem and feel free to contri
