CYD-RFHat enclosure with battery

This is a remix of https://www.thingiverse.com/thing:7331473 with a battery compartment added along with a mounting hole for an external WiFi antenna. Future additions: improved holder for stylus and a slot to hold the mini GPS board (away from the DIP switches), plus baking to hold the ceramic GPS antenna in place (currently hot glue). Used 4 10mm M3 hex head mounting screws on the back of the case to secure the boards. You'll also need 6 6mmx2mm magnets to secure the case
