Table saw blade alignment with calipers

Simple tool allowing to use common calipers (16mm wide) to measure saw blade alignment. It will fit in 19mm or wider miter slots (width adjustable with 2 screws), in my case, miter slots are 19.3mm wide. I was able to get consistent measurements with 0.01mm accuracy.BOM (I used what I had at hand):1x M3x10 hex head screw2x M4x20 or longer countersunk screw1x M3 heat insert (OD: 4,5mm, length: 5,7mm)2x M4 heat insert (OD: 6,5mm, length: 6,4mm) Usage:1. adjust width screws, so the guide fits the miter slot tightly without any wobble2. place calipers against the edge and tighten down holding screw3. place support piece under the other side of calipers
