Bushings for Wiha screwdriver rack by spencerwebb

I like the Wiha screwdriver rack that spencerwebb published, but I have a lot of other small drivers besides my Wiha's that I'd like to stuff into the same rack. I made a pair of bushings that push into the holes in the rack so that small drivers don't fall through and larger drivers don't lean-over. These bushings make the rack universal.
