I have an old craftsman 10" saw that has a 16 mm by ~7 mm miter slot. I copied your slide design but made it to fit the miter on my saw. However when I took it off the printer I realized the 50mm bolt was now too long since the miter on your saw was deeper. So I printed a spacer for the knob. I will post a remix with my parts for anyone else with the same saw. Thanks!
Black parts printed on a Dremel 3D20 in Dremel PLA at .2 mm at 205 deg C. White parts printed in Dremel PLA on my acrylic Prusa clone from flea bay. I recently got the Dremel and it came with a bunch of filament. I usually use the cheap inland stuff with good success.

Black + White
Dremel recommends 220 deg for this filament but it oozes way to much I print it anywhere from 185-205.
