Propcutter hex insert

Both of my printers and slicers (Slicer PE & Simplify3d) skipped the M5 thread on the propcutter_small file. They just basically left a whole bigger than 5mm, which defies the purpose of the item.
Because of this I quickly sketched my own version, which allows you to pressfit an m5 nut into it. I guess you also glue it in, but it wasn't necessary for me.
