This is a cylindrically-shaped dice tower that can be expanded as high as you can stack it! Once assembled, the middle sections can be twisted to change the path of the dice. Supports Settlers of Catan and standard D6 dice. Assembly demo: https://youtu.be/IiKTh4Hh0eY Dice demo: https://youtu.be/jdS_LXVL-bAFace it, your life just got D20 times better... You're welcome! :) Oh, and if you print this, please kindly click "I Made One" and share pictures and videos! I love that stuff!Oct 21st, 2015 update: Added the Spiral module... updated the Arch module and deleted the Banister module (dice always got stuck in that nook at the bottom!)... Enjoy! Oh, and "Happy Back To The Future Day!"Oct 30th, 2015 update: Replaced both Battlements and Spiral modules with improved versions. The Battlements modules now have 2mm walls and the Spiral module prints way easier (without taxing your poor printer with steep and thin angles like the previous design)
