These easy to print scatter terrain bits are meant for our growing 18mm scale miniature range and will fit nicely into your 1" grid maps. I designed these pieces to assist with quick battlefield dressings during our games of Wayfarer and Wayfarer Tactics.
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...)
I printed mine with rafts, though it shouldn't be necessary if your calibrations are good. I printed my RockFormationA with supports, though you could try going without and it might be just fine.
