The Lilygo T-Echo Meshtastic communicator, [https://www.lilygo.cc/products/t-echo,](https://www.lilygo.cc/products/t-echo,) comes in a case but all three important buttons are exposed to being accidentally pressed.  This bracket protects the device from such accidental button presses and provides a carabiner mount:

• The touch-sensitive button is enclosed from four directions.
• The two system buttons are protected by a 2mm raised gate.
• The top of the bracket provides a carabiner mount to fix it to backpacks or hang it in your tent or at your campsite.
• The antenna cutout is compatible with both the original T-Echo antenna as well as several other antennas I tested.

Printing the bracket:

• Print with the flat side down.
• Use supports for the carabiner mount.
• Supports for the M3 holes is optional; if printed with supports, use an M3 screw to push them out from the other side.
• Layer height: I printed this in 0.2mm.
• Any material is fine, but for outdoor use materials such as ABS or ASA may be preferable.

Mounting the bracket:

• Use two M3x10mm screws to mount the bracket to the M3 holes at the back of the T-Echo device.

I also include the FreeCAD file used to create this design.
