Double wide single outlet shelf

Based on the model from the Original Outlet Mini Shelf by Makidev, my wifey and I wanted the shelf to be bigger to allow holding wider items. I edited the STL to double the width of the shelf. Our electrical boxes are surface mounted, so we needed a 4mm spacer. I've included the 4mm spacer as a separate object in the STL. Recommended approach is to shrink/grow the spacer to your required amount, and then merge it with the base model. Then print on an angle with a small brim.
