I won't be able to get to my friend's house that has a 3D printer and make these for some time. I'd be interested in purchasing those 3d printed parts that you have in the video above if they will fit an 18650 Battery, Switchcraft 2.1mm Power Jack, 2W 28mm 4ohm OD Bass Speaker, proffie board, and 4-40 threaded rods. They would need to be the diameter for a graflexshop 1.9 / original graflex. Can you message me on this?
