Seej is an Open-Source tabletop wargame based around 3D printing.
This archive contains almost everything you need to start playing Seej. You'll need 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.
Rules for Seej are at http://www.s33j.net
Keep it friendly. Show no mercy.
Seej patient zero. Barbie Armor Designer, artist, worst programmer ever. Mostly illiterate, but has minimal competence in spoken Mandarin. Not real clear on Ohm's law.
