Undercounter Receptacle Mounting block

I’m looking for someone with a 3d printer to create me a triangle block that I can mount under my cabinet and then put plug mold on top of the mount
This will be a complete triangle no openings
I will need 13 feet total, in 12, 24, 30 and 36 inch lengths
I will need a 12” sample to make sure it will work

Here is the type of plugmold I will use
