Hex die holder

Hex die holder, for a 1-7/16" die. The hex cavity is .500" deep. Included is the file for the lower section, without the 1" hole, .125" thick. Using this tool to clean up printed threaded items, I didn't see the need for any die locking screws, slight pressure towards the work works for me.
Sketchup 2017 requires a radius when drawing a hexagon, so I use this site to calculate the radius from the "across the flats" dimension:
