Coffin-shaped Electrical Box Switch Plate, many configurations, with OpenSCAD source

Single, double, and triple switch types, rocker, toggle, duplex, and blank in most combinations (except the triples which have too many) are included as STL files. OpenSCAD source included so that you can product more triples in any combination.

You can select which opening type you want in each position.  All measurements conform the the NEMA WD 6-2021 standard.

If using the OpenSCAD source, also download “switchplate-coffin-v2.json.txt” and remove the “.txt” from it (printables doesn't allow uploading of JSON files).  It is the OpenSCAD customizer configuration file for the different types of plates.

The two-device plates require a printer that can handle a model 243.5 x 243.5 if rotated 45 degrees

The three-device plates require a printer that can handle a model 320 x 320  if rotated 45 degrees.
