Lilygo T-Echo bracket case

prusaprinters

The Lilygo T-Echo Meshtastic communicator, 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.
