Yep, it's the vehicle from Moon Patrol alright! The buggy is scaled for 15mm-18mm gaming, though it certainly doesn't have to be used as a gaming miniature. If you want one in 28mm scale, scale the model up by 166.6% (or so).
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...)
P.S. You can find the original design here on TinkerCAD. I'd love to see some remixes!
