My ratchet set came with a very flimsy blow molded insert which has become brittle and fell apart. I have created a replica which holds the parts securely. The overall dimensions of the insert are 372mm x 70mm (14.64" x 2.75"). I have split it into two pieces (174.5mm and 197.5mm) for printing on a mid-sized printers. The two parts can be inserted separately or glued together.
