25mm Paper Mini Base

This base is meant to be used with paper for highly customizable and inexpensive miniatures. I can't be bothered to print minis for every random creature in a grid encounter, but want my D&D players to see what they are fighting.

Scale a character/monster image to fit a 23 mm width (height is up to you). Add 4 mm to the bottom, which will nest inside the base. You can also add additional length for tabs if you want to fold the paper under the base and tape it, if the fit is not quite right.

Edit: Version 4 includes additional height on the sides for grip and includes a directional arrow to indicate which way the mini is facing, should that matter. The opening was also shrunk to 22 mm width to give it a little more structure.

Edit 2: Since the side pillars give extra support to the paper, version 5 has a 0.4 mm thick layer below the paper so it does not fall through or need to be taped. The slot has been reduced from 0.4 to 0.3 mm to give just a little grip.
