Summary

This model is part of a video tutorial I am working on in FreeCAD. I am creating a video while working through some of the issues of designing and printing a part that fits well with non-printed parts.

The video tutorials are here:

Arduino Case Using FreeCAD - Part 1
Arduino Case Using FreeCAD - Part 2

This is a work in progress. If you have better approaches ( like datum planes ) let me know and I would be excited to make updates and changes. Or if you find mistakes, please let me know either here on Thingiverse or over on YouTube. If there is interest I will make a github for the files. It would be wonderful to have a tool-set specific to making cases.
