Sister site Mallyable has released a couple of interesting printable 3D models that have an astronomical theme. The Big Dipper Pendant and Constellation Pegasus Pendant both have pinholes in the same configuration as the actual stellar patterns. Adding simple string or chain of your choice makes the pendant wearable.
These are not the first astronomical products at Mallyable; the Orion Pot (and lid) displays, of course, the constellation Orion on its side.
