I was looking for a bit box with some longer bits.

I came over the DeWalt box, but I was so annoyed by the inlays that holds the bits. 

It was unpossible to quick swap the bits because of how the bits were hold in place. 

You can see the original ones in the left lower side of the picture, you have to slide the bit in from the upper side with the correct orientation. 

My printed versions have tilted holders for the small bits to reach and change them quickly and are held in place by 10mm x 2 mm magnets underneath.

The manget slots were closed with a drop of hot glue to secure them in place.

You don't need supports, bridging works well.
