This is a ceiling mounted pulley system I designed for my PSVR on Tinkercad. I used 22mm bearings in the rollers.
A spare curtain rod that measured 16mm external diameter, by 13.8mm internal diameter.
I used 1/4" by 1 1/2" bolts to mount the wheel to the hanger, with a dollar store retractable key holder inside the hanger, to keep the wires at tension.

My TV is lower then recommended camera mounting height, so I made a simple "Clamp" that screws to the wall to hold the camera. Requires provided articulated mount to work properly.

I printed: layer height 0.2
2x Curtain rod hanger
2x wire roller + bushing - May need more depending on how far you intend on having the wire hanging.
2x 15.7mm pipe clamp.

In my pictures is also a headset holder:
