Included is a set of Civil War Infantry in sack coats with a variety of headgear options including Kepis, Forage Caps, Hardee Hats, Slouch Hats, Tall Slouch Hats and Western Hats. Where appropriate, hats have a variety of brims (straight, curved, “sloppy”).
The models are scaled in 15mm, but can be scaled down to 10mm. When scaled to 90%, they will match up with Kallistra/Warlord "Epic" figures.
6mm prints have been successful using a Phrozen Sonic Mini 4k but some printers may well run into issues (namely difficulty printing bayonets) going that small.
For adding facial hair and other accessories, please use the free Figure Exporter Blender file I've hosted for here on MyMiniFactory.
