Jib arm rest support

I needed a support for the Proaim DVC 500 camera jib while mounting the pan-tilt head, camera, cable, making adjustments, etc. Usually I used a chair's backrest or a table, but few times there where none, so I designed a U-shaped support that fits snuglly onto a standard lights stand with a 1/4 inch thread. The U-shaped thread was made by a handtap.
