AgOpenGPS Micro V4.1 smaller enclosure

The enclosure from the original github was a bit too bulky for me so I made a slimmer version. 

The two parts lock together with some 1.7mm filament No Screws Required ! !

I Have not tested if the enclosure gets hot without active cooling but since the original also didn't have any active cooling and the low power consumption I think it'll be fine.
