I liked how Riffnshred's design looked but it was too flimsy and broke really easily and I liked the mechanical mechanism of erer2001's screwdriver (bit holder only) but the bits didn't fit too nicely. So, I combined the two into one that in my opinion, is the best screwdriver bit holder for any screwdriver bits. it not only feels nice, but more closely represents the original LTT bit holder mechanism.
