Red shipping blocks

I would like to print more of these 2 part shipping blocks that came with my Taz but I can’t find the files. Does anyone know where they are? These are great little pieces of hardware and I want to save time in not redesigning the wheel.

The two part rod clamps are here: http://devel.lulzbot.com/TAZ/2.0/production_parts/printed_parts/stl/
