Parametric Weatherproof Project Box

A few months ago I started building ESPHome sensors and I needed to place a few of them outdoors or near a water tank. I went through a few iterations, but came up with this design, It´s parametric, in the sense that I arrived at this shape through parameters, I don´t know if it will survive other shapes.

The standoffs and holes are setup for a STEREN 405 Phenolic board, because that´s what I have, but should be modifiable to whatever you need. 

The grommet/seal has 2 holes that should be modifiable to whatever you may need, I used them for data and power cables.

I set mine up vertically and there should be no water ingress whatsoever, however if set up horizontally, there might be.
