My own design for a Meshtastic/Meshcore Heltec V3 walkie-textie that also holds a power switch, 18650 Li-Ion cell, & TP4056 charge controller. As a bonus, everything is held together by a single M3x10 pan head screw.
Bluetooth/Wifi
For those of you who are unhappy with the existing 2.4GHz (Bluetooth & Wifi) antenna on the Heltec V3, I've integrated space for a Slim Jim style 2.4GHz antenna. Based on my rudimentary tests, this external antenna for the Bluetooth & Wifi improves signal strength by 10dBi.

I cut off the bottom lead (red) and soldered my wire in the space denoted by the blue square below. Do this BEFORE you push the clips into the 3D print.
