I like to use miniatures in my games of Dungeons & Dragons, and admittedly, I have quite a few of them. Even so, when it comes time to hunt down the player characters with an entire gnoll war band, it can be hard to come up with six gnashers, 4 slashers, a dozen bipedal hyenas, and a partridge in a pear tree... thus I created the Force Multiplier. Use one miniature to designate an entire squad of baddies, all color coordinated. Now for less than a dollar I have sextupled my forces.
I print mine in different colors of filament but I imagine one could just as easily paint them up.
BaseInsert and OriginBand are designed to fit on the base of a medium sized creature from the official DnD miniatures lines. Custom bases should be easy enough to develop.
