Arduino MKR GSM 1400 Case

Two-part case for an Arduino MKR GSM 1400. Requires x4 M2x20 screws or two zip ties as a work-around. Has slots for zip tie mounting and cut outs for IO ports and micro usb. I will be adding more versions soon two allow access to the other ports as well as allow for use with heat set inserts. Please comment if you would like to see any specific changes. Remix as desired.
