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. Final size of the case: 46mm x 87mm x 18mm and only around 60g with the board and the battery. 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 will need 4x M1.6 5mm. You can use the screws that come with the board, just drill the holes a little bit wider. 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.

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!

EDIT 1: 

• Included a cutout inside the "Front" part for a laser cut acrylic sheet with 54mm x 30mm. You can use acrylic sheets up to 1.8mm to protect the epaper screen.

EDIT 2 (following requests on reddit):

• Included bottom option for battery's height up to 11mm (adds 5-6mm of height compared to the slim version, can use the same M3 x 14mm screws).
• Included frame option for SMA antenna (adds 2mm height compared to the original one with FPC, needs M3 x 16mm screws).
