The file 'Makita LS1212 Miter Saw Insert 3D Printer Model' is (stl) file type, size is 24.6KB.
Miter inserts were all chewed up, so I designed new ones as close as I could to the original. Should be easily modifiable if you want to try 0 clearance insert.
To connect the two pieces, I had played with the idea of a puzzlepiece-like connector, but any weight in the middle would cause it to buckle. The connector as designed now is glued in place in both tracks in the middle, making it more sturdy. Print 2 connectors
