Zero Clearance Block/Backplate Festool Kapex KS 120 EB

Prevent blow-out on the back side of your workpieces with this simple solution. It clips right into the “half-circle” recess in the middle of the fence bracket. Once clipped in, unclamp both side fences and pull them inward, until each fence captures the “ears” of the insert. Lock your fences in position and you're ready to start cutting.

In testing, this worked great, but I discovered if you make a lot of angled cuts, this will expand the kerf line and you'll be back to having a bit of tearout. Solution: print multiples, and keep one dedicated for straight-on 90 degree cuts. 

Printed using Bambo PETG-HF, face down (fence face down), with supports, three wall loops, and 30% gyroid infill. 

Why is this so cool?

• Easy to install and remove
• Self-centers into the fence bracket half-circle very precisely, so you can remove/reinstall and your kerf line will still be exactly in the same position as before
• Doesn't require any other modifications to the original fence
• Retains depth of original fence (you don't need to add an auxiliary fence), so the Kapex's original clamps will work without issue 

Remix of @Dudadz3d's Zero Clearance Fence Insert for the Kapex 120 REB, designed to fit the KS 120 EB fence. Be sure to print the version that is compatible with your saw, as the fences are different.
