Parametric case with snap-on fittings

This box was inspired from Adafruits Pi's case.
I decided to do some flexible openscad baseline that could help on many projects.

Add your own custom openings fitting your needs. Note that even though is parametric, I have not tested all possible changes, and may break.

In future I may add the legs circular shapes as these are quite nice.

Update: after long waiting for a cutter 1.5mm now this is finally built. Watch tolerances if you use CNC and not laser cutter. I may do an update to handle a 0.02 tolerance, now its snuggy, if using end mill dia >1.5mm you may have to trim the convex 90 corners with a cutter.
