Flexi HDMI Coupler $3.49
I found this flexible coupler while shopping for a simple fixed 90 HDMI elbow. Just a dollar more than a fixed elbow buys 180 degrees of rotation in two axes. I bought an extra one to use SOMETIME in the future. Should be 19 connections inside. Good for flexing connections through a robot arm joint or some such nonsense? Maybe even for use on a TV. https://www.ebay.com/itm/324931707383 $3.39 free ship!
