If any of you has ever wanted to mount a laser transit or similar to a photographic camera tripod you've discovered as I did that the size of the transit socket is much larger than that of a camera. The adapters I found online were either for microphone stands/booms (wrong size threads), or much more costly than I would have expected so I designed and printed this one. It's not the prettiest thing but it works well. It may also have that added benefit that if the transit gets knocked over it would likely break the adapter instead of the transit socket unlike what would likely happen with the metal adapters (the socket on my transit is plastic). Note: The little knob on top was added in hopes that it would help prevent the adapter from getting stuck when tightened.
