Paper Miniature Base

This is a miniature base for paper miniatures for tabletop RPGs such as D&D, etc. It is the common 25mm (1 inch) diameter.

I've used the basic dimensions from tstine's "RPG Creature Base" but I've redrawn it with some changes:
* Angled sides like most miniature bases, because I prefer the look
* A narrower slot (0.6mm) - more suited to resin printer tolerances than FDM. This fits light card, paper, folded paper or laminated paper fine.
* Curved edges to the slot. Again, I just prefer the look.
* Magnet void in the bottom. Will accept a 6mm x 0.5mm magnet with a dot of glue. I find this very handy for storing and transporting miniatures.
* Chamfer (only 0.5mm) on the bottom. This effectively eliminates elephant's foot when printing these flat on the plate, and eases release if you don't have a flexible build plate.

If you are cutting miniatures out, the covered area of the slot is 18mm wide and 5mm deep.
