Small PCB Mechanical Coupler

A small PCBs coupler.
I used this to fix an USB/RS232 converter on an Arduino Pro Mini board on the USB side. The other side is connected to the Pro Mini board by header connectors.
It's a simple and effective solution for development work. Probably not suitable for a 'production'/definitive product...
As it's an OpenSCAD source file, adjust the parameters (commented) to suit your needs...

Note:
Set either the RndPCB1CornDia/RndPCB2CornDia or the RndPCB1CornCut/RndPCB2CornCut variables to choose between the cutout or rounded corners (or set all to 0 to use square corners)...
