The author remixed this model.
Per my usual, I found something I needed, found somethings that I liked, and mushed them all together. Here we have a Spade Bits holder (designed for Bosch Spade Bits, but worked just fine for the cheap ones I bought at the local hardware store) coupled with the MegaMounts backing. That allows you to place them on a pegboard without needing screws, or IKEA Skadis without screws, or to your wall with screws.
I have added the pegboard, Skadis, and screw mounts for you to choose which would work best for your situation.
