My attempts to make transportation disks for the ‘Keep’ scenario attracted the attention of David from Iron Mammoth Design.
Being a handy sort, David laser-cut the disks and added a couple of layers of steps before giving them a quick paintjob.
Then - generous chap that he is - he sent me a set! Here they are, with a little extra highlighting and a sprinkling of snow.
Thanks very much Iron Mammoth!
