Wio Link board holder v.1.0

Modified this Wio board holder by BjarneMatzen link: http://www.thingiverse.com/thing:1546003 to suits my need.

This only holds the WIO Link Board with two screw mounting holes. The screws will be use to hold the top cover (i'm planning to use acrylic). I'm also considering to design a top cover instead of acrylic.
