I use this to prime and paint my miniatures.
Whilst printing you can add sand, small gravel or anything really to weight down the base.

It might not be pretty, but it sure is handy!

I use 4 walls en 20% infill since I tend to drop things and 20 bottom layers for weight, but feel free to use what suits you and add as a comment to show others.

Feel free to remix this.

Printed 16 at a time on my ender 3.
