The attachment on the handle accepts the GoPro quick connect bases. It would work for a variety of camera housings though, as they all seem to use the standard ¼ 20 screw. If you just wanted a small handle I also made a base that goes over the end. I plan to use this to attach an inexpensive flashlight I bought on Amazon.
Fitment worked well, sorry for the under extrusion in the attached photo's I wanted to finish this print before opening up the printer in case I couldn't finish it before the contest ended. I called it Chiquita because it's bent like a banana. The leg works as print in place as long as you print the tray standing up on that end. I may work on that more in the future as this was my first time trying a hinge which was fairly difficult to get something that worked. I pause the print on the handle part to embed a ¼ 20 nut.
