About this 3D model
Derived from thing [102562](http://www.thingiverse.com/thing:102562) by TheKretchfoop. In stead of the hole for the push pin, it has holes for two small 4x4mm round magnets. Also attached is the openscad file I used to customize the original STL. So if you have different sized magnets, just update the openscad and regenerate.
