Made this pair of drill bit holder attachments for my trusty DCD800 since I like having half a dozen bits on me.
They're contoured to fit snugly and very securely, with an M3 screw (10mm long) and protruding nubs holding them on the same way that the belt clip attaches. Left and right attachments are unique due to the design of the drill. They're actually quite stable without screws entirely. I suggest using a material with some flex like ABS or ASA, but just about anything will work.
I had some pan head M3 screws kicking around so that's what I used in the photos but grabbing some flat headed screws at your local hardware store for a few cents will be even nicer.
