Doorstop

Inspired by all the doorstops! Here's another!
This one measures 3.5" in diameter and has a 1.5" slot in the base to accommodate the door. Also, the bottom is angled for a snug fit.
(Note: I did a lousy job sanding this. I'll upload a better picture once I get this done.)
For CNC routing, measure the gap between your door and the floor, then raise the Z axis accordingly. Allow 1/8" for the model.
Ideas for printing:
- Make it out of glow in the dark plastic.
- Make it hollow and add a battery pack and LED light.
