3 Jaw Chuck for Power Tool

While I really liked buho29's 3 Jaw Chuck, it lacked a mounting system. So I rebuilt close to it in Fusion 360, and changed the base plate to have a 7.2 mm hole to take my small power tool. Then I changed the holes to take 3 instead of 2 screws to allow a sturdier connection.

Lastly, I made alternate jaws and put markings on each as well as the chuck.

The jaws can't be swapped with buho's design.
