hex bit holder

I added a tiny brim under the supports for the 2 pegs.
I remixed the back mount 2 ways.
One way will let you clip it onto a wire rack shelf with a 27mm face or lip.
The other way will let you bolt it onto a 25.5mm round leg for a wire rack shelf.
I used a couple 2.5mm X 12mm ss socket head screws and 2.5mm nuts to hold the shaft collar together
