We had a similar thing before, in that Ghamak produces files to print your own miniatures at home. There are currently 24 miniatures available there, with 3 of them being Greenskins. There’s also Patreon releases, which, if I understand it correctly, later go to the shop.
You can find all these at Ghamaks website. Prices vary, the Goblin Napoleon is 5,50€, the Orc pirate is 7,32€. Ghamak also has a Facebook page you can subscribe to. All pictures above belong to Ghamak
