TrueTrac Track Saw to Irwin Quick-Grip Clamp Adapter

These allow you to use some cheap clamps from Home Depot with the TrueTrac track saw system.  I really like the TrueTrac line of products and I'm sure they sell some nice clamps but I just needed these in a hurry so I designed them in Fusion 360 to work with the clamps I had nearby which are the Irwin 4 ½" Quick-Grip 35lbs clamps.  These tiny clamps seem to be plenty strong for what I need.The part is not super easy to print, to be honest.  But it is designed to use the original screw and nut from the clamp.  I was able to print it with no supports when I have the hex nut cutout facing down.  I used a .6mm nozzle with 4 perimeters (~2.4mm walls) and 15% infill.  This made the overhang where the clamp bar goes print pretty good for me.  Layer height needs to be .2mm or less if you print in this orientation and you want the screw to engage the nut. Now I happened to print in Polycarbonate which is probably way overkill but it prints so nice I couldn't resist.  I did most of my design revision prints in PETG though and it seemed fine.
