Festool Kapex 120 REB Zero clearance Fence Insert

Keep your Kapex from blowing out the grain on the back side. I've seen similar items, but they were bolted to the saw only worked at 90 degrees. This is easily removable and also allows the saw to move freely while installed.

Front face should be down on the bed. PETG suggested. I use 25% honeycomb infill, no brim, and 4 walls.
