Vỏ hộp lắp cột cho Meshcore Heltec V3

This is a mast enclosure for a Meshcore repeater, or something else.
A Heltec V3.x will fit and there is a special place for a 14500 li-po battery
the usb port is accessible. so you can power the device from a solar panel or just 5V from a power supply.
The battery is mainly there to buffer the current draw. My Meshcore repeater is powered by the 5V coming from the coax to my ADSB receiver antenna.
The Bias-T of that antenna cannot handle "large" currents. Now the battery gets trickle charged, and when the Meshcore repeater needs to transmit, the power comes from the battery.

ASA is the preferred filament for outside. because it's very resistant against UV. But I guess black PETG or even black PLA will do the job for years,
