adapted 3DDIY's design from https://www.thingiverse.com/thing:4571944

adjusted to fit my ryobi tracksaw tracks, with a total length of 165mm (very tight fit, my track measured 163mm after trimming the splinter guards), and a thickness of 11mm

Printed with bambu strength profile, which seems strong enough for me. tolerance worked with some generic PLA i have lying around. needed to use some thin metal ruler to pry open the nut, and once it's loose, it works perfectly.
