Gridfinity Small Modular Screwdriver Bits Compact

There are two versions available: one with holes for magnets and one without.

The model accommodates one handle with a bit, plus space for 10 additional bits. It is stackable.

My handle, when not fitted with a bit, is approximately 132 mm in length.

My design is more compact, catering to those with fewer bits. It occupies a 4x1 space rather than 4x2. Additionally, the handle cutout has been slightly expanded.
