Raspberry Pi 2 Stacking System

A stackable cradle for the Raspberry Pi 2 & Raspberry Pi 3. Cannot call it a case as there are no sides and lid included. Assembly post printing is straight forward, just stack more bodies with Pis in them. If you want to link adjacent cradle bodies you will need to print two links.

A friend wanted me to print [redogre](https://www.thingiverse.com/redogre/about)'s [Pi 2 stacking system](https://www.thingiverse.com/thing:694992) but with the link as part of the main file it would not fit on my Vector 3's build plate. The solution was simple enough, split the model into two files:

- **RaspberryPiStack_Body_v3.stl** which is all you need to print to build a tower of [Raspberry Pi](https://www.raspberrypi.org/)s. This features an updated body that has stronger attachments to its columns and some fixes to the geometry. Hopefully these will help eliminate some slicer anomalies that were observed.
- **pi2stack_body_v2.stl** which is all you need to print to build a tower of
