Yet Another Filament Spool Adapter

Between the differences in the various spools sizes and my inability top use callipers, I keep getting them wrong. So as an excuse to experiment with the materials springiness I've come up with these. The first few lines have most of the important parameters like basic diameters and number of spokes. Print two and snap into your filament spool, then slide them on a M8 or 5/16" rod. You might have to adjust the center diameter a bit depending on your printer settings.
