Customizable Project Box with built-in perfboard

I just learned about the old radioshack p-box kits on [hackaday](https://hackaday.com/2018/12/14/retrotechtacular-remembering-radio-shack-p-box-kits/). The idea is a box with regular holes for electronic components. So the box itself becomes the perfboard/breadboard platform.

So I built a customizable project box.

You can specify the dimensions, wall thickness, and pitch (hole spacing).

Print face down and you will not need any support.
