The file 'Symmetric-arm Socket Wrench 3D Printer Model' is (stl,scad) file type, size is 20.9KB.
I use this as a collet wrench on my mill. The symmetric arms reduce the chance I will pull the spindle out of alignment when tightening the chuck.
I included 1/2", 5/8", and 3/4" stl s, and an openscad file if you want to customize. I use the 5/8" on the DW660 router with my Shapeoko 2.
