This is a personal design. The Miter Saw Handle Fits a Craftsman Model #137212370, I printed this with 6 walls and 98% infill using PETG on a Creality Ender 3 Pro. This was my first time using CAD any tips would be welcome. Fill free to remix the file as needed. I hope this helps someone else out with this saw.
