Miniature Base Set 4 (25mm - 35mm figures) is a set of six different types of trapezoid bases, including prison cells, altar, gears, cargo box, symbols, and skull bones. These models are complete and do not require support structures. The prison cell is large enough to accommodate another base, allowing characters to be taken out. This is an excellent 3D model library material, only showcasing one piece for now. Downloadable full original format file materials can be viewed.
