Modifications for 1/2" rod O'Cello (angled endpin, endpin cap, square knee pads)

thingiverse

I wanted to use a solid steel rod for the middle of my O'Cello, as well as a 1/2" aluminum tube for the endpin, so here are a few modifications to make that possible. "imperial_endpin_rect" is the piece that connects a 1/2" rod to another 1/2" rod at a 10 degree angle, so the endpin can be collapsed beyond the bridge of the O'Cello for storage. The caps are for the 1/2" aluminum tube. The fit is a little loose, but you can glue them if you want. Also I didn't want to buy a new piece of metal to attach the knee braces, so these are square ones designed to fit on the cut end of the 1/2" aluminum tube.
