Lego Breadboard Mount

Mounts a small solderless breadboard ([like this one](https://www.sparkfun.com/products/12047?gclid=CPjT0Ni34MQCFUZqfgodcpQAVw)) on Legos. It is also the equivalent of a smooth topped 5x6 thin brick.
If somebody prints it, let me know how well it (doesn't?) work. I'll be more than happy to tweak it and make it better.
