D&D Large Creature Flight Base 50mm

I created this because I wanted to have a base for large flying creatures with a dial to show the height, and also wanted it to have teeth so it wouldn't slide around, becoming inaccurate. It comes with the base and ring, to be used either with a creature that already has a hole for a similar base, or with the top part, which can be glued on to the stem of the base. The stem's diameter is 2mm. The numbers are also large enough to be legible on most print settings.

Let me know what you guys think, I'm still a relative CAD noob, so any comments or makes are appreciated!
