Mitre Saw Angle Finder

Use this to get the exact angle on the mitre saw. i.e., Most of the time, corners aren’t exactly 90 degrees. So this divides by 2 and you just have to align the top part with your mitre saw blade.

Print one of each part except for the “Top Gear x2” and “Snap Ring 10mm” as you need 2 of each. No hardware needed except if you want to lock the angle finder. Then you need a M5x25mm hex screw and M5 nut and print the “Knob M5” and “Washer 6mm”. For the "Knob M5" add a pause in the slicer at the proper height to insert the M5 nut.

PLA+, 0.4mm nozzle, 0.20mm layers, 3 wall loops, Random seam position, 15% infill. Right and Left Arms need to be printed faced down. If you want the numbers to be more visible on the Right Arm, just add a pause in the slicer and change color. Easy to assemble, just look at pictures.

I had the best results with Jayo PLA +. PETG left some play in the gears so it’s a little less accurate. Made this with Freecad.
