Simple case designed to accomodate an Arduino Nano and a NRF24 radio module. It has a simple lid with an opening so the antenna part is at the exterior (in case you have a module with the antenna modification). The case has another opening at the bottom so that the USB port is acessible (for programming or power).
To make the "stick" the small as possible, it can be a bit of a challenge to insert the Nano and make the connections to the radio, so i suggest to insert the Nano first, up-side-down, and make the connections afterwards.
The lid is a bit a work in progress so at the moment it doesnt have any kind of way to attach it to the main box.
First layer printed at 0.30 and subsequent layers at 0.20. Check your tolerances and module dimensions!
It doesnt need supports but check your bridging settings.
