Free 3D-printed support eases USB-C access for RAK10724 LoRa boards

Jejeronimo posted a free 3D-printable angled support for the RAK10724 on Cults3D, aiming squarely at one of the most annoying parts of a boxed-up Meshtastic build: reaching the USB-C port when the node needs charging, reflashing, or bench testing.

The model is sized at 150 x 100 x 70 mm and is presented as an angled support and enclosure piece rather than a decorative shell. The listing includes both STEP and 3MF files, which makes the part easier to modify before printing or adapt into a larger enclosure. Its tags, including Meshtastic, MeshCore, LoRa, RAK, RAK10724, support, and electronics board, place it firmly inside the same DIY off-grid communications world that keeps Meshtastic builders looking for practical hardware fixes.

That practical angle matters because the RAK10724 is not a toy board. Meshtastic documents the RAK WisMesh 1W Booster Starter Kit as a high-power Meshtastic solution for extended mesh range, pairing the RAK3401 WisBlock Core based on Nordic’s nRF52840 with the RAK13302 1W LoRa transceiver module. Meshtastic says the setup can deliver up to 1W, or 30 dBm, transmit power with improved receiver sensitivity. The hardware docs also note USB-C support, LiPo battery support, and a 5V solar input option.

Meshtastic also warns that the 1W RF stage needs a stable 5V supply because the 3.3V rail cannot provide the surge current required. That makes access to the connector more than a convenience. On a node that might be running from USB, a battery, or solar, a support that changes the board angle and reduces strain on the cable can make day-to-day maintenance far less awkward.

The new print sits inside a broader enclosure ecosystem that already exists around Meshtastic. Meshtastic runs an enclosures repository as a file hub for hardware enclosure information and CAD references, while RAKwireless offers 3D-printable enclosures under a free-to-use, noncommercial license that allows sharing and remixing with attribution. NodakMesh also frames Meshtastic enclosure options as a mix of 3D-printed cases, weatherproof enclosures, and commercial products, with antenna feed-through often becoming the weak point.

That is why this small angled support lands as a useful utility part rather than a novelty. For a RAK10724 node that needs regular access, the difference between a cramped port and an easy reach can decide whether the board stays simple to service or becomes a nuisance every time the cable comes out.
