Inventor exports my STL-Files in a wrong size. You have to set the size by hand. Usually it's just a dot, that has gone in the wrong direction.

This one is a part of a set with actually 2 but in future maybe 3 parts.
1st Part: Drills 1 - 11,5 mm
2nd Part: Tapping Drills M3 - M14
3rd Part: 12 - 13,5 mm or higher (maybe - let me know, if you want it)

I haven't printed those yet, cause i'm printing drillorganizers for my drillpresschest.
