HTC Vive Ceiling Hook
I bought retractable reel holders to run my Vive cable overhead, but the carabiners that came with it slid all over the place and were really just porly made. I tried using cable ties to keep them where I wanted them, but adjusting them was a pain. Before I decided to go overhead, I was using RichWP's belt clip. I basically took his round clip for the cable into TinkerCad and added a block on top that the cord reel wire could go through and then a slot to center the cable on the clip.
Now, the retractable reels stay connected to the cable where I put them and it's easy to reposition them, plus, it seems do a better job overall keeping the cable from getting wrapped in the reel wire.
