Parametric Light switch Cover. Originally designed to cover up some drywall mistakes that the normal sized plates didn't cover. Decided to add a Parametric option so that way you can choose how big a plate you want and how many switches are in the unit. A one size fits all if you will!

Using the customize feature you can:

• Edit the overall Height using the first option.
• Edit the Width between the edge of the outermost Light switch hole and the edge of the overall switch using the second option.
• Edit the Depth of the side edge of the plate using the third option.
• Edit the spacing between the Light switch holes using the fourth option
• Edit the amount of Light switch holes using the fifth option.

All values are listed in inches but if you click on the model after using the Generate button, the model will show the values in millimeters. 

Added a screenshot with easy-to-follow lines to show exactly where the measurements should be for your use case. Make sure to use that as a guideline when inputting the values to get the correct sizing you would like.
