ok, since the 3D printer can't do the CEIT logo on the top of the case I've redesigned it to have the roof missing in the shape of the logo. I'm not so sure about the support structures for the letters, I still can't decide if it looks good or bad.ceit_raspberry_pi_case_top_correct_scale.stl
Just a small adjustment to the model for the top of the raspberry pi case.
I've finished a full draft of the case and battery pack with a method to attach them together. I didn't get to see if all the spacings of the raspberry pi case were correct because the printer was having some trouble, but from the one component that did print (albeit very warped), The spacing between some of the ports seems correct.

In the past week this project has come together quite well. The basestation is running on the Netduino Plus receiving packets from tags and sending them over the network using the UDP protocol.The basestation (seen below) can be reproduced at a fraction of the cost of the OpenBeacon EasyReader POE II, using just a few widely available components. Although the netduino does not support power over ethernet and only one radio chip is used (slightly less throughput) it is a viable low cost alternative.
It has been 2 weeks since I started working on the base station. The hardware consists of the ‘Netduino Plus’ and a Nordic nRF24L01+ 2.4GHz radio package from Sparkfun. The Netduino Plus features on board Ethernet and SD card reader, perfect for use in this project as it is intended to have all data aggregated on a networked server.
