Camera Tripod screw
thingiverse
The idea of a plastic printed screw for securing the camera didn't sit well with me. Instead, I envisioned holding a sturdy 1/4-20 hex bolt from the hardware store in its place. Given that my design calls for a 9/16" screw, you may need to use an even longer bolt depending on your tripod's base size. To ensure the bolt stays put, gluing it into the thumbscrew might be necessary.
