OpenSCAD Door Holder

Customisable snap in door holder.
I rebuilt this thing http://www.thingiverse.com/thing:1639345 in OpenSCAD - you can resize almost everything. I did some different mounting positions to fit different door and frame shapes - pls see the STL files. All STLs can be build from the OpenSCAD file, see the last 5 lines.
Edit: Some nasty little errors sneaked into the SCAD, it's updated.
