LoRa DX-LR03 + UART Box

It’s simply an enclosure for the DX-LR03 radio and a UART-to-USB reader, consisting of two parts (the main box and the lid).

No screws are needed—it fits together by pressure. It has vents to allow some airflow in case the radio gets a bit warm, although that has never happened to me.
If you add a cable grommet, you can hang it in different places or even from your laptop screen ;)

Printing instructions

You can download the full model or in separate parts. I use an Ender 3 V3 with standard settings, 0.14 mm layer height, and tree supports for the USB slot (Enable small overhangs for the USB slot.)
