3D printed 140mm sphere with 25mm survey prism. Includes 3/8"-16 brass insert for mounting to heavy photography tripod. Includes adapter to mount to standard 1/4"-20 tripods. Also includes neodymium magnet base. Does not come with tripod. This 3D printed part will have some minor aesthetic defects such as rough surface layers, stringing, blobs & zits, holes, or warping, so it may not be pretty, but is still functional.
