NRF-TXT - Standalone Meshtastic communicator (Heltec T114)

This is a case designed to build a standalone Meshtastic communicator using the Heltec Mesh Node T114 and the M5Stack CardKb. The goal of this project was to create a compact, easy-to-print design that remains functional and durable. It also supports additional features like GPS, a buzzer, and an environmental temperature sensor. Additionally, it accommodates folding antennas that can be tucked in for improved portability and compactness. https://youtu.be/Z4FBOKlFj2w?si=kYsXvYxZ7pFTXzTp ###List of Materials: - Heltec Mesh Node T114 + GPS + Screen - $38.80  https://heltec.org/project/mesh-node-t114/ - M5Stack CardKB - $7.95 https://www.digikey.com/short/v8wjcvb3 - Silicone Cover - $12.00-14.00  https://harukitoreda.etsy.com/listing/1772533422/cardkb-silicone-cover - 4000mAh Li-Ion battery 125054(12x50x54mm) - $9.99 https://www.aliexpress.us/item/3256803444293288.html https://a.co/d/iMcOw71 - 3V Passive Buzzer 9042 - $2.51 https://www.aliexpress.us/item/3256806074013807.html?channel=twinner https://a.co/d/3LovgP7 - BME680 - $15.07  https://a.co/d/hAfowoO - 868MHz - 915MHz 3dbi Folding Antenna - $3.02 https://www.aliexpress.us/item/2251832778598150.html - 16mm m3 Hex Socket Head Cap screw -  https://a.co/d/aFIBnWE - 28 AWG Stranded Wire Spool -  https://a.co/d/4YyacXU ###Printing instructions: I designed all parts so that they do not need much support other than tree supports. They are on the position that will get you the best possible print. ###CardKB Instructions: 1. Make sure to remove the Groove port connector that comes built-in to the CardKB, this is necessary to be able to cover the keyboard with the silicone cover. 2. Solder wires as follows:  ###BME680 Instructions: 1. The sensor must be soldered at the same time as the keyboard since both boards must be plugged to the the same SDA, SCL and Ve pins. 2. Solder wires as follows:  ###Buzzer Instructions: 1. Solder positive side of buzzer to pin 1.01 2. Solder negative side of buzzer to GND 3. Configure External notifications to work from pin 33 for the buzzer
