This is version 1 of a meshtastic case I'm developing, I'm pretty happy with the fit to the board and the antenna connection, walls may still be a little thin and I need to adjust the buttons some, but it's functional for now.  It will fit a 3000 mAh battery and I like this board b/c it requires no soldering for the GPS.

Let me know what you think!  I'm interested in comments around how much bigger I could make it before it's too much, as right now external dimensions will have to increase to add any more aesthetics or functional features to it.  the cross-members that clip onto the lid are probably not necessary based on the friction fit of the board in place, but they help make everything fit tight without parts slipping inside the case.

Current dimentions (l x w x h) are: 75mm x 50mm x 27.5mm

I leverage 4 m3 x 20mm screws and have not added material to provide for counter-sinking yet.
