Seej is an Open-Source tabletop wargame based around 3D printing.
This archive contains almost everything you need to start playing Seej. You'll ne...ed to supply your own pennies and elastic bands, though.
The recent proliferation of inexpensive filament printers with smaller build platforms requires the advent of a smaller Seej engine, so I've added the Marshmallow Mangonel to the kit. The classic catapult gets improvements inspired by community feedback, too. It's all compatible with older prints, and is much, much more accurate.
