About this 3D model

This block will connect with other Interconnecting Robot Prototype Blocks I have published on Thingiverse. The purpose of this block is not to hold anything but to allow other blocks to be connected to each other. Designed in Blender 2.69. I will upload a source file in due course. UPDATE: 9 Feb 2014 Added a more simple version with fewer cut outs. Printing showed that removing support from internal cuts was difficult. Both version are available.
