Case Enclosure for NGFF WWAN M.2 Key B to USB 3.0 Adapter Board with Dual SIM

This is a simple case for the generic WWAN "NGFF M.2 to USB 3.0 Adapter M2 Key B to USB 3.0" adapter.

You can find such an adapter on Amazon, eBay, AliExpress etc. https://www.aliexpress.us/item/3256804635197714.html

The two small clips on the top case may need to be cut slightly smaller (ONLY cut down the the top and sides if needed, DO NOT cut the bottom side) depending on how your supports print (or the holes they go into can be made larger, and again ONLY cut down the the top and sides if needed, DO NOT cut the bottom side). See the last picture for what I mean by “clips”.

There are two holes for the PWR and WWAN leds, as well as a hole for the reset button. Both SIMs are accessible, but may be quite hard to get at with your fingers. I suggest you use tweezers or something but your nail will be fine.

You will need an M3x16 button head screw to securely close the case.

There are two versions of the bottom:

• WWAN M.2 KEY B TO USB WITH ANT & DUAL SIM - POSTS v13
  This version is the normal case bottom
• WWAN M.2 KEY B TO USB WITH ANT & DUAL SIM - POSTS v16
  This version has four exterior mounting points sized for #6 wood screws, so you can mount it to a wall or piece of wood etc…
