I felt the need to have a more evil-looking dice tower as the game master, so I designed this fang dice tower. I figured I'd throw it out there for anyone else who wanted to print and use it themselves as well. You'll get some underhangs beneath the stairs that need to be trimmed, but since the model works well, and I'm putting it out for free, I'm not overly concerned about them. (Netfabb Online Repair can't fix them, nor can the tools on my PC, but you can see the finished product above.)
I printed it at 0.2mm layer thickness, and with 15% infill to ensure the stairs had some strength to them. It was designed to print on a 6" x 6" x 6" print bed (Lulzbot Mini).
I used videan42's unicorn horns to make the crossing horns over the stairs. You can find that here if you like it: https://www.thingiverse.com/thing:8671
Here's a video of me testing it after printing: https://youtu.be/OrMjyNYG6-I
