I made this model to fit my “Xool” screwdriver and bit set – however, this set is pretty generic and a lot of brands carry the same thing. 

Specifically, this model holds the 9 rubber bit holders, the screwdriver, and the extension part in a 2x4 gridfinity bin. 

Also included (as of 2/19/2025) is a version that takes up one less grid space by having an irregular shape.
