I used a great model from myminifactory for the basis of this dice tower (https://www.myminifactory.com/object/3d-print-star-wars-darth-vader-30-cm-tall-60500).
This tower requires no supports to print, and as sized should work with 19mm dice pretty easily. If you need to use larger ones, and have a big enough print bed, just scale it up!
