Bolt-Sorting Sieve Screen - Spacer

Info on the Bolt Sorting Sieve, and links to other screens, can be found HERE This is a spacer for the above bolt-sorting sieve design. The spacer is intended to add some height to a given "chamber" in the sieve to allow for longer fasteners, or space for some additional shaking goodness if you have it particularly full (although obviously still limited by the number of 'pores' per screen').
