Here’s my first full on design. A Dungeons and Dragons Flying Creature Miniature Riser.
For those who aren’t familiar with D&D, it’s often played using minis, and there are often creatures who fly that must be represented by those minis. The goal of this little device is to lift the mini up and indicate how high it’s flying. For example, in the photos below, the creature can be shown to be flying 53 feet in the air. It has notches cut in the sides for the marking chits for the height, and measurements from 0 to 9999 ft.
It slots together very smoothly. If the slots were a little tighter it might be better, so consider that if you download this and use it. I just glued the acrylic together and it looks good to me.
