Summary
I dig wargaming like Frostgrave and Warhammer Kill Team, but also don't keep a ton of space dedicated to terrain... so, since I have a Glowforge Laser Cutter, these are what I built to be able to slap on a table and play a game well, and then collapse easily into a shoebox size container.
These are all cut off the 1/8" MDF sheets that you can buy at Home Depot... I think all of this is from 2 sheets that were 2 feet by 4 feet each. If you change up the material, you might need to tweak the line art.
They all snap together easily and are surprisingly very very sturdy. The only real "assembly" is the "bridge" pieces which are kind of a sandwich so you can slot them over the points they connect in.
Please credit these if you share/edit them, and if you modify/expand the line, I'd love to see what you create :)
(If you're brand new to laser cutting, know that you'll certainly have to lay out these assets to fit your material)
Have fun!
