Heltec LoRa V3 Meshtastic case with SMA antenna hole

A rugged node case for the Heltec WiFi LoRa 32 V3, the board most Meshtastic beginners start with. It measures about 50.2 x 25.5 mm with a 0.96 inch OLED, a USB-C port, a u.FL antenna pigtail and a 2-pin battery connector. The case is 62 x 34 x 22 mm with 2 mm walls, a 15 x 10 mm window for the OLED, a USB-C slot, two 3 mm holes for the reset and user buttons and a 6.5 mm hole for an SMA bulkhead so an external 868 or 915 MHz antenna screws straight on. A cavity under the board holds a 1000 mAh 503450 LiPo. Prints flat in two halves with M2.5 screws.

Meshtastic nodes come in dozens of board revisions, which a shared download cannot track. In SpeakCAD you describe your board, preview the case free in the browser, move the SMA hole or fit a bigger battery in the chat, and download the STL.
