Kobalt Sliding Compound Miter Saw Zero Clearance Insert.

I was tired of the horrible tear out created by the stock insert. The gap was at least 1/2" wide.

I finally sat down and spent some time with calipers and Fusion 360 to get a new zero clearance insert modeled. It took 3 tries to get the holes lined up just right.

Totally worth the effort!!! I have included the CAD files so you can fine tune to your liking.

Designed for the following saw, but may fit others.

• Kobalt Lowes 10-in 15-Amp Single Bevel Sliding Compound Corded Miter Saw with Laser Guide
  • Item #358938
  • Model #SM2507LW

Details

• There is about 1 to 2 mm play in the long direction
• The underside has 45 deg cut outs for each side to be used cutting angled miters
• I printed with three perimeters at 0.7mm wide - ensuring that the blade wouldn't cut into any of the infill parts.

Notes:

1. You may need to slightly enlarge some of the holes to get the screws to fit. They lined up just perfectly for me, but everyone's printers are different.
2. After making the first cut to make the slot, use a chisel to scrape off any built up PLA from the top surface.
