This is a zero clearance insert for the Ryobi TSS103 10 inch compound sliding miter saw. It's separated in two parts to fit most build plates. I made two versions, one of which has a solid block beneath to stop any dust from falling beneath the saw through the gaps in the insert.

Print everything with 100% infill. The version with the solid block took me 167 grams of filament.

Be careful while doing the inital cutout, as most 3d printing filaments will gum up and stick rather than cut smoothly.
