Summary

Created a platform comparable to some of the clear plastic ones sold online (although more open for airflow) for the Raspberry Pi B+. Next I will print in clear ABS.
Update (10/11/14):
I uploaded version 3 which appears to fix a problem with the board shifting too much when plugging/unpligging. Tried to print in PLA and many parts broke off, so I would recommend to print this in ABS only for strength and durability.
