Pill bottle parts rack

This is a set of components that can be used to make variable size and shape racks for holding pill bottles(33mm diameter) full of small parts.

I looked at http://www.thingiverse.com/thing:564108 and decided I needed more flexibility and heft.

Also looked at http://www.thingiverse.com/thing:275326 which took up more liner space than I had.

UPDATE: Mounting brackets fit into either cores or edges and has a screw-hole for securing it to walls etc.
