Enclosure for HELTEC LoRa 32 v4
This is a simple enclosure for the HELTEC LoRa 32 v4 with space for all development needs. There are many cases/models that are better if you want a portable and fully closed case. This enclosure should be ideal if you want to plug in external gadgets (Like a solar panel or battery) and want to use the GPIO header on the device. The enclosure provides protection from bumps and shields the contacts/board from unwanted contact.
Feel free to change and remix it as you want, just throw in a comment here and show what you did!
What is still in WIP: Ideally I would want to add a mount-point for both the 865Mhz antenna and the satellite antenna, since I still use a very basic antenna I will get to it once I have a better one. It could also be prettier, but since I am in the process of learning FreeCAD it is rather basic (also I know that the FreeCAD workflow I used is not ideal, in the next Projects I will use more advanced features). The buttons are very basic too, but since I rarely used them I do not really care (a spring mechanism would be nice). Also a small hole in the bottom of the battery cover might be useful for batteries that have their output on the front. NOTE: I also saw a small error with the battery cover, will fix that as soon as I get to it.
You can find the FreeCAD file attached if you want to make changes. Let me know what you think of this model!
Features
Purely with pressure fit, no screws necessary
HELTEC board does not move around
Easy(er) GPIO pin access
Adjustable and freely changeable with FreeCAD
How to print
Use supports for the battery compartment. Place all models on their flat side. Clean up the model well after printing, the tolerances are ~0.2mm each side for pressure fitting (You might need to use your knife to cut away all blemishes and support leftovers). If you just want the main body you can leave out the battery compartment and battery cover and use it as-is (Not that the pins are exposed in this small configuration).
How to assemble
Pressure fit everything together!
2 Buttons go into the main body (after the HELTEC v4 board), the lid goes on top. Button placing can be fidlly, so it might need some attempts. The main body with lids and buttons can be used without the battery enclosure, but if you need the battery case you can pressure fit the whole body in there.
