Angle 90 degrees 40x50 mm

I always missed a small 90-degree square to set the table saw or check the angle of the material after cutting. Metal and accurate are expensive. I made the project and it works.Arms 40x50 mm. Foot 10 mm.I printed it in PLA.Layer 0.12 mm.I recommend it, it makes work much easier, e.g. in wood.
