A slip case for Heltec Visionmaster E290:
Easy to print, comes with several variations:
There is room for a small battery even in the slim case; I have a 200mAh battery in my home node as a short-term backup although it is normally permanently powered.
Select the parts you need, and print without supports.
Use a pair of 2mm x 5mm screws to hold the cap; I salvaged mine off some old equipment I was recycling.
Pad the board at the cap end if it is loose after fitting.
The board model used in designing this is here:
Note: There was a early E290 board revision with sideways facing buttons.. the main case here is for the current shipping model that has rearwards facing buttons (if in doubt, zoom in on the pictures of my board..)
But if you do have the early board with side-facing buttons: there is a case version which has a finger-sized cutout to allow the buttons to be pressed directly.
The author marked this model as their own original creation.
