Zero Gap Kerf Insert for Ryobi 10" Sliding Compound Miter Saw with 12" Cross Cut TSS103
Suffering from tear out with your mid-range sliding compound miter saw from Ryobi and it happens to be model TSS103? You're in luck, because that's what this thing is for.
After you print it and install it, you just cut right through it, and bam, perfect cuts with less/no tear out. I'd only use one printed kerf plate for each angle of cut though, otherwise you're going to end up right back where you started from with the OEM kerf plate.
Since this is a cut through, infill is going to be an important decision. 100% is safe, but I don't think you need to go all the way.
As for build plates, odds are good this won't fit on yours. It fit on mine rotated at a 45 degree angle with millimeters to spare. I would split it between the middle screws so you have 3 holes on each using your slicing software of choice, or just omit the last 1/3 of it entirely if you don't need it.
