The bin divider is used to separate the bottom half of the stock bin that comes with the ToughSystem 2.0 6-Compartment Small Parts Organizer (DWST08020) or the ToughSystem 2.0 Full-Size Organizer (DWST08040). Works well in conjunction with the ToughSystem Nesting Bins (sold separately). *Designed by aclmnts on Thingiverse.
