Summary

Simple passive wire cam setup
Works great with a gimbal.
Can be moved using a slope or a rope to pull on the wire cam...

Uses 3x 686ZZ bearing (6x13x5mm) and one standard 1/4 inch screw for the gimbal/camera mount.

Print 3x time the Puleys. (The middle one is optionnal)

Also included my solidworks files if someone wants to improve it...
