" The wealth of Moria was not in gold… or jewels…"
Her are some basic caves or mines structures. Very easy to make takes some time to print.
Some basic part can me maybe made of hardboard or polystyrene but if you have the patience all can be printed. The parts are made for a 20 x 20 cm bed but can be resized to 15 cm without any problems. Also slicing is a option.
Its in 28 mm scale so good for lord of the rings / hobbit, warhammer, enz..
There a lot of different parts to puzzle you own mine, big or small.
Can be done grey for caves or mines but also green for hills with holes and caves.
Just ask when you need a building plan for the mine in the picture.
