Its made of card and loads of matchsticks, plus some PVA glue to hold it together and loo roll to hide the shonky joins. It took a couple of hours to cut out the bits and assemble them
Yes, I know it's not painted; it'll get more PVA and some sand and gravel first.
It's designed to hold a four-stand Maurice unit on 1" square bases. It sits on a footprint 4" square, and is about an inch high.
I'm going to make another, if only because I need two of them for the One Hour Wargames 'Fortified Defence' scenario, which is coming up soon.
