1/4" screw used to secure the cable guide to the camera rig.

This will hold basically any cable in place of varying size. I've been using mine for about 6 months now and it hasn't broken or gotten loose once.

Filament

I used PETG for better impact resistance than PLA, but any filament will work. ASA is technically the best filament for this print, especially if you take photos/videos outside. But I don't think it's necessary. 

Print Orientation

Keep the print orientated in the way that my print profile has it. Which has the cable guide arms being printed flat on the bed for maximum durability. This does mean that support is necessary but even with support it's barely any filament.
