Wall_Plate_High_Profile_Blank

I'm looking for a wall plate to be custom-made. I need it to be made out of plastic and the dimensions should be customized for the purpose of functionality. This wall plate needs to be durable and able to withstand wear and tear. It should be of a high profile and have a blank face or surface. The finished product should look professional and be of top notch quality.

The images attached are of the off the shelf model with a height of 12mm (I would like the increase the profile to 14mm)
