Makita CXT Bitholder

I like to keep my bits on driver, b/c i don't need them when i'm not using it. I have a set of longer bits that are difficult to carry around in pockets or belt and i tried to ziptie them to a drill, with little luck. 

Only mounting point in Makita drills is the screw hole for the belt hook for lefties. 

I don't have TPU so i used PETG, which is a bit too hard for this. 

Also the holes are tight for the bits.
