Remix of https://www.thingiverse.com/thing:5345697. Adapted to fit into the Gridfinity system.

Gridfinity 1x2. Can stack onto Gridfinity divider but can't have divider stacked on top of it.

Hole at top to allow for 2x magnets (2mmx6mmx6mm) to be pushed & hot glued in.

Bolt holes for M4, M3, M2.

For marker inserts use source (optional, I don't use them). https://www.thingiverse.com/thing:5345697
