Adjustable board support stand

**This needs to either be printed with 0.10 layer height or variable layer height** It's an adjustable board support for when working on edges of boards, or when needing an extra hand for supporting or holding a board upright. It's designed to be put together with a M5 hexnut and an M5x12mm bolt. Be aware that if you make variable layer height, you need to reduce the layer height around the part where the ripples of the base piece are, since they probably won't print if the layer height is too high.
