I had a cheap (7.49) set of Harbor freight Titanium Hex Shank Drill Bit Set, 13 Pc. lying in the bottom of my tool box and decided the only way I was ever going to use them is if they where organized and in a case. So I got out the calibers and opened Fusion 360.
This case has a few parametric features like the size of the hex and the distance between the bits.
The lid is snap fit.
V4 updated with new height on upper part of case - seems V3 was just about 2 mm to short for the largest drill bit :)
