Revised Cam Lock Design

I used the Cam Lock design from 58 webbing - https://www.thingiverse.com/thing:879225 and did a bit of modifying.

2) I changed the cam to have a smooth section when turned 180 degrees. This helps in feeding the line in and in removing the line. All you need to do is rotate the cam and the line will slip out easily.
3) I designed it to have either 2 solid sides or 1 solid and 1 open side. Just substitute one of the cover plates.
4) I used 3mm
