M6 thumb screw
thingiverse
One of the M6 screws on our tripod ruined it's thread by many years of abuse. I was going to buy a M6 bolt and print a handle, but things worked out that I just went and printed the whole thing. It works well enough for now and locks the head as expected. It's a bit long, and I'm sure won't be 100% strong in the long term. It was knocked up in Solidworks.
