I got special permission from Gendemik to share my remix! I had to choose “Original, I made it” to publish the remix  as I am not able to link to the original design as its license does not allow sharing and remixing.

AGAIN the BASE DESIGN IS NOT MY CREATION!  I just got permission from Gendemik specifically for my REMIX that allows me to share it!!

Dont miss out to check their other creations and leave them a like for allowing me to share my remix with the world!: Gendemik | Printables.com

You can find the original design this remix is based of here: GDMK Heltec v2/v3 Diddy (Smallest case project) Meshtastic inspired by Gendemik | Download free STL model | Printables.com

I am aware that there are two little holes right above the lower screw holes of the front facing cover when printed. They wont be visible once screwed to the back shell and also wont cause any instability issues! 

The manual Power switch can be used to cut power coming from the battery to be able to complete switch off the device  or to mute the buzzer. 

A whole week of runtime on a single charge!  (1000mAh battery) 

Buzzer for notification

Takes pretty much any SMA compatible Antenna 

GPS connector  can be de soldered for more room but is not essentially necessary.

10Kilo Ohm Resistor or higher to pull down the GPIO port connected to the mosfet, or you will drain your battery faster then you can say “ oh wow that piezo speaker actually kind of heats up O.O” 

if you upload your own sketch variant of meshtastic I guess you could use an internal pulldown as well.
