This is the first iteration of my foldable travel Dice Tower. Easy to print compact. You can easily store a full set of dice down the shoot and close it up. It is support free printing. You might get a little bit of squiggles on the inside of the shoot, but they can easily be clipped off. For better hinge function on the top piece, you could place a little bit of support on the indentation that touches the build plate. It probably adds 2 minutes to the print time. I also left a little room under the insignia on the top piece for anybody that has know how and wants to personalize this with some text. That makes it great for a gift.
