I like these straight hex drivers as a complement to my Bondhus ball-end drivers, and needed a spot for them on the ol' pegboard.
Because they've worked so well for me on other designs, I decided to use my pegboard rivets for attachment. They allow the part to be printed in an optimal orientation without support, and the rivets hold it tightly against the board with no ‘jiggle’ when you're trying to take a tool out.
I recommend printing the rivets in PETG or ABS for the added flexibility.
