Summary

I made this adapter that converts a standard camera thread (3/8 - 16) to (1/4 - 20) thread.
16 and 20 are the number of threads per inches (TPI).

There is a Hex and a Knurled version. I think HEX would be easier for some printers to print.

Be gentle with the threads. It's not that strong, but strong enough to work. I chamfered the 1/4 base to resist better any moment.
