Gridfinity Retrofit Square

Make any existing non-gridfinity organizer bin/object plug into a gridfinity base. Directions: 1: Place the Gridfinity Retrofit square(s) into the location(s) where you want your object to plug in. 2: Put some glue (i.e. CA) in the middle of the Retrofit square(s) and then press your object where it needs to go until the glue sets.
