Bit holder for 9 screwdriver bits

After i could not find my bits for several months, it was pure luck to finally find them. I decided to keep them very close to the place of use from now on...

PS: The inner size of the hexagon is 6.32mm (bits are 6.35 nominal). You might need to play with horizontal expansion and/or part scaling to get a perfect fit for the bits. This will depend on your printer and settings.
