Heltec Tracker LoRa Meshtastic Enclosure V3 (Updated 2-5-2026)

I purchased a LoRa module from Amazon to get started learning about Meshtastic, and I realized after receiving it that I needed an enclosure for it. I didn't realize how easy it would be to set up. I would assume if you're here you probably have what you need, but just in case I have it listed below. Check out the parts list. I keep a box of M3 screws and nuts on me at all times and keep it stocked.

Version 2 Changes

Extra support was added to the middle section to hold the Tracker Module more securely. I also thickened the middle sections ends and beefed up the LoRa antenna mount so it will be more sturdy. The slide switch was updated to be shorter, and the cutout for the switch is slightly shorter so there is no gap when the device is on.

Version 3 Changes

I added switch and antenna support to make those sections a little stronger.

Build Instructions

3D print the parts that you want to use. I have a Bambu A1 that I can easily change colors on, so some of the parts are split to allow different colors to be used. I printed the entire thing without supports. The Enclosure Middle is split to allow it to adhere to the bed, but I included a solid model in case you want to try that route. There are two sizes of buttons. If you want a recessed RESET button, print the small one. If you don't mind both buttons being small or large, print two of the size you desire.

Note: Print the top and bottom at 100% infill for best results. If you continue to have issues, I will consider making a thicker one.

If you printed your screen insert separately, glue it onto the top enclosure and make sure that it is fastened and dry before continuing.

Place your two 3D printed buttons into the top enclosure.

Install the Heltec Tracker module into the top enclosure face down through the LCD window and route the GPS antenna into the GPS recess. Clamp the enclosure over the antenna.

Secure the external LoRa antenna to the middle enclosure, and tighten the nut. 

Solder the battery to the switch as shown in the photo. 

Shorten the positive lead to the battery and solder it to the common of the switch.

Solder the JST ZH 2 pin connector's red wire to the Normally Open (NO) side of the switch. 

Finally, solder the black wire from the battery directly to the JST ZH connector. Use heat shrink to insulate those connections.

Slide the 3D printed power switch slide into place, but do not place it into the ON position.

I secured the switch to the top enclosure using spare M1.2x8 screws from an old 3D printer homing switch. I don't have a clue where to source these at a decent price. You could use a dab of glue to secure it if you don't want to or can't find the screws.

Plug the battery into the Heltec Tracker board and cram it into the enclosure. MAKE SURE YOU HAVE AN ANTENNA ATTACHED IN CASE IT TURNS ON! You don't want to destroy your radio before you ever get to use it. 

Finally, put the bottom of the enclosure on and fasten it together with the scews and nuts. I used 4 M3x18 screws and nuts to secure the enclosure. It's cheaper just to buy the kit and use the kit for building other stuff.
