Edit: This case has been superseded by the squared off slim case, I highly recommend it over this older design. If you still want to use an RY836ai I have a version of the squared off slim case that can hold one.
Updated version of this case.
Last one that will support the RY835ai.
Labels for AHRS orientation and antenna frequency.
Lots of room for a ground plane for your SMA antennas.
Has a mount for a 30x30x10 mm fan.
LED holes on both sides so the LEDS will be visible on both the pi2 or pi3
If you like this design and want to thank me my paypal address is firstname.lastname@example.org I can also do any customization.
