Adaptor tripod 1/4-20 UNC sang 3/8-16 UNC

I needed something quickly to load my SeeStar S50 onto my tripod, that had a standard 1/4-20 UNC mount, I printed this out at full density with PLA, works perfectly.  You should probably print it out in ABS if you plan to use it for a while … be careful if using expensive electronics, get a proper adaptor.
