Gridfinity Xacto Knife Tray Insert (3 slot)

Xacto Knife tray insert for Gridfinity

Rather than dedicating a 1x3 (gridfinity units) exclusively as an Xacto knife tray, give this insert a try. The insert fits inside an 1x3, or can be used stand alone on your work surface.

Optional models: Model B (squares at both ends)
