Old Design
This a d20 jar I am working on to hold my large collection of gaming dice. This is a work in progress: I have not printed it yet to confirm the working model. Open to suggestions.

2 pieces: top and body. Should be scalable, depending on your need and print bed size.
Onc version has raised text,
