I designed an all-in 3D printed table saw throat insert. It features changeable dovetailed zero clearance strips that are easy to make from 1/4″ birch plywood. The insert allows full range of movement of blade and splitter (height and tilt angle). It has leveling feet for perfect alignment with the table surface, a safety tab, and fine fit adjustment screws. It can be printed on most common household 3D printers. While it is tailored for my particular table saw, I’m hoping that the design can be tweaked to fit other left tilting saws.
