Heltec V4 Solar Node 3D Models and STL Files

This collection gathers 3D printing files built around Heltec V4 boards used in solar-powered mesh nodes. It covers enclosures, battery holders, GPS housings and mounting hardware, so you can assemble a node that fits your own board revision and power setup. Most items are small enough to print on a standard 3D printer. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«Heltec V4 Solar Node 3D Models and STL Files»

The files fall into a few groups. Solar enclosures house the board together with a panel and a battery, while simpler holders carry only the board or a single 18650 cell. Some designs add room for a GPS module or a display, and a separate group covers brackets and rail caps that fix the node to a mast, a rail or a wall. Mesh firmware builds appear as their own variant, since the layout of a Meshtastic or Meshcore node often changes where the antenna and ports sit.

Before printing, open the author's page and compare the stated board revision with the one you own; Heltec V4 and V3 differ in port and antenna placement, and a case made for one may not line up with the other. Check the number of parts, how they join, whether screws or inserts are needed, and whether the model expects supports. The material and settings the author lists matter for outdoor use, and photos of real prints show how the lid, cable openings and panel mount actually come out.

If the results look narrow, try related wording: solar node, LoRa enclosure, mesh node case, battery tray, GPS housing, mast bracket or rail mount. Searching by board name, by cell size such as 18650, or by firmware name usually returns different sets of files, and combining a case search with a mount search helps when you plan a full outdoor build.

FAQ

Frequently asked questions

Which board revisions do these files cover?
Titles mention both V4 and earlier versions, and some models are written for one revision only. Compare the port, button and antenna positions on your board with the openings shown in the author's images before printing.
Do these enclosures include the solar panel and battery?
The files are printed parts; panels, cells, boards and wiring are separate. Some designs leave a recess or bracket for a panel and a slot for an 18650 cell, which the description usually states.
What should I check about printing an outdoor node case?
Look at the wall thickness, lid fixing and cable openings, plus the material and settings the author lists. A case that stays outside also needs a way to keep water out of the panel and connector areas.
How do I find a matching mount for a node case?
Search for the mount type you need, such as mast bracket, rail cap or wall plate, and check the hole spacing against the case you plan to print. Many mounts are published as separate files from the enclosure.
