Openscad case for LIlyGo TTGO T-Beam boards supporting both SMA and IPEX antenna versions.

Contributions welcomed, feel free to send a push request for considerations. Build process improvements... new hardware revision supports

This was created to bring together various good ideas I seen in various cases but aiming for ease of printing

Also targeting:

• Hight tolerances for loose 3D printers
• Slits for mounting straps
• Support both IPEX and SMA antenna style
• Support OLED
• Support both zip tie or M3 or M2 screws to hold case together
• Able to prop device at an angle to view screen on desk easily

IPEX

SMA

Improvements considerations for the future

• Add a grill on top of OLED screen to prevent screen damage
• Add buttons as an option to help reduce enviromental ingress damage.
• Make a version that is enviromentally sealed (no buttons perhaps) with rubber seals (But how to charge?)
• Allow for various GPS antenna style and mounts

Building

Requires linux or windows running linux subsystem to build the scad files.

Assembling the base station

You should use the IPEX version of the t-beam.

Used two IPEX to SMA-KY 5CM adapter. One for the lora antenna. One for GPS.

Intent is to be used as a base station on a garage or a car booth.

Below is a visual representation of how it can be assembled.
