So while we wait for the last few things to assemble the prototype SunLeaf modules I've been working on 3D printable case concepts. The goal is to develop two cases, an outdoor case with ruggedization/weather proofing and an indoor case. So far I've just been modeling a simple concept, just a lid and and bottom. The bottom mount sthe SunLeaf module with access to the back ports through cuts on the case back. The top fits into the bottom with friction fit tabs and has cutouts for all the sensor ports. Right now its just a simple housing but will evolve over time. Here is what the initial concept is looking like right now:

Back cutouts for solar panel, battery, and USB ports:

Look at the whole case:

So far that's what the case is looking like. The next thing is going to be adding antenna mounting for the ESP8266 module, at the time I started working on the case CAD I didn't have the antenna's in from the mail to measure them, so in the coming days I'll be adding an antenna mount. As for an outdoor case for SunLeaf its going to be radically different, I want to mount the solar panel and battery internally and have the entire thing well sealed. This may sound crazy or ambitious but I also plan to 3D print the weather proof case as well as the indoor one. I think it can be done if we get creative with material choices and clever design. Stay tuned, there is much much more to come for SunLeaf in the coming days: assembly! Testing! and More!!
