This set of miniature terrain pieces was designed for Wayfarer Tactics, our fast, modular (as in "fully customizable") miniature gaming rules. If you want to check it out, it's totally free here on our site, so give it a download! If you want to print 28mm scale versions, just scale them up by 166.6%.
We've set up a Patreon page for anyone who's interested in helping to fund us so we can keep making free and open sourced games like Pocket-Tactics, Wayfarer Tactics. and others, not to mention the growing catalog of gaming miniatures that you can use for whatever you want! (Psst... we take requests and commissions...)
