The relatively new 'Mortal Gods' game is using some special 3-man bases, and of course, somebody has made 3D-printable versions. Mortal Gods use minis based on 25 mm bases, and as I base most of my minis on 20 mm washers, I had to re-scale the file to 80% to make it work.
As you can see below, the re-scaled sabot base fits like a glove for my 20 mm based minis.
I am probably going to get Mortal Gods, or the fantasy version 'Mythic' at some point, but I am printing the bases for One Page Rules Age of Fantasy Skirmish, where most bread-and-butter troop types come in groups/units of three, so these are actually perfect for that game, too.
I am going to print some round 'light troop' 3-man bases, too, but right now I focus on the triangular 'formed up' bases, as I need six or seven of those for my first test games of OPRAoFS, the first hopefully occurring Monday afternoon. Well, 'need' is probably an exaggeration, as the minis in a group just have to stay within a certain distance, and moving three minis at a time is not that big a deal, but printing some bases fitting for the game is just too big a temptation, as it instantly means some extra geek points! 😆
