Holder for transparent front

A holder that can be mounted to a transparent front, e.g. a plexiglass sheet or inside a transparent box. It is mounted using four nuts and bolts (I think the dimensions are off at the moment, please check if they fit yours). It is generated from OpenSCAD, and you should customize it to fit your dimensions.

It was designed to hold a digital hygrometer in a [Filament Storage Solution box](http://www.thingiverse.com/thing:743280).
