I had some connectivity issues with my Raspberry Pi on the floor while running OctoPrint. I thought it might help to get the WiFi dongle higher so I stuck it on the end of a USB extension. The logical next step was to attach it to the end of a stick. The 'thing' is designed to grab on to the strain relief on the female end of an Amazon Basics extension. It has a hole for a 3/8" dowel.
Added a base to mount to the top of my Kossel Clear.
