SandWars Sand Castle molds

3 Star Wars inspired sand castle moulds based on simple geometric shapes that will tessellate individually or together as part of a larger base. I've added some images that may help get you started.

Design:
The buckets have a 2mm wall thickness for durability and have sloped angles on all sides to allow the moulds to be easily removed from the sand, there are also a number of 1mm holes in the top of the mould to allow some air in when the mould is removed, while they're not going to hold
