This is a simple gridfinity holder for a set of V blocks measuring roughly 3" W x 2.4" D x 1.325" H.  It uses a 4x2 grid.

The model shown is printed with eSun PLA+ Bone White for the base and a 1.5mm lip at the top using Polymaker PLA Pro Metallic Chrome for a contrasting accent.  This was done with a layer height modifier for the last 1.5mm.
