For a project I was working on, I was well on the way to designing a
custom enclosure. I did a lot of work on the base to hold the
PCB. When I was looking around for something to help with a detail of
the rest of the enclosure, I came across mrWheel's YAPP_Box project,
https://github.com/mrWheel/YAPP_Box, which does everything I was
planning, plus a lot more. So, I am not even using this design myself,
but some of the OpenSCAD things I figured out along the way
(especially threaded spikes and donuts) might be useful to someone in
some context.

This is a parametric design for a flat base to hold a PCB. It has 4
posts for mounting the PCB and also to provide stand-offs from the
base. If you 3D print this, don't forget to allow for shrinkage of
