Summary

Case for Heltec Wireless Paper, there are so few cases for it, so I decided to make one and share it here.

My goal was to make it as slim as possible. The case is for a 1500mAh battery with 30mm x 78mm x 4mm (max of 32mm x 79mm x 5 mm) and to get rid of the bulky SMA antenna, I used an FPC one (they work great!).

You will need 4x M3 14mm screws and 4x M3 nuts. To fix the board into the frame, you need 4x M1.6 5mm. You can use the screws that come with the board, just drill the holes a little more. The M1.6 was what I had around, sorry.

Heltec chose the worst place for the buttons... I made a bendable part in the frame to touch the buttons from the side. It is working, but I think they are a little weak. It's a nice start, but still a work in progress. I'm also trimming some tolerances.

The bottom part was printed with semi-transparent PLA, the only way to allow you to see the LEDs, because the battery is in the way. Again, Heltec chose a bad spot for key components...

Happy printing!
