Vase Mode Dice Tower

I thought I would set myself a challenge and see if I could design a spiral shaped dice tower that could be printed in vase mode. It might not be very big or strong, but it is quite fast to print compared to other towers and it does not use much filament.There is a small area near the top where the overhang is just on the limit and it does not print very clean, but otherwise works ok. No base for it yet, but will maybe make one for it later if there is interest.
