Case for 79x39mm panel mounting modules

These little modules are pretty common, either as power supplies or monitoring instruments. They fit a standard(ish) panel cut-out mounting hole is 76.5mm×39.2mm .

While there are lots of cases for the DPS3xxx/5xxx modules, I could not find anything compact to house a "Combometer" which is a useful 100V 30A battery monitor so I designed this. This is a little smaller than most to be a tight fit, deliberately so it doesn't rattle about.

I also added two powerpole options (I use powerpoles everywhere) which are developments from https://www.thingiverse.com/thing:1424702 - there is no binding post option and there won't be, seriously reconsider if you use them as it's just too easy to wire things backwards.

There is no sophistication to this design, I can't get on with FreeCAD so I used Tinkercad to develop it.
