Welcome to ARCS: Vol.2 3D Printable Sci-Fi Terrain! Following the success of my four previous Kickstarters I am very pleased to present the next part of the ARCS campaign trilogy: a set of modular corridors, rooms, and ducts for you to print on your resin or FDM printers. The parts have been sized to fit on small printers too, such as the Elegoo Mars 2 and Prusa Mini.Â
