Summary

This 1/4 " Screw 29mm is a remix of https://www.thingiverse.com/thing:4873019
.
The buttom wheel was cut short and the winding was lengthened. Sorry for my bad english, you see what it is, nothing secret here. It fits cameras pretty well, I use it to attach my own created devices to it. As the winding is so long, it can easily cut to fit the need.

Preferebly printed with ABS ore other strong materials, to avoid breaking.

EDIT:
V2 - Screw now has some additional material from the winding to the knob for better equipped not to break.
Keep my bad english.
