What is Faraday Enclosure Generator?

Faraday Enclosure Generator is a free browser tool that builds printable cases for electronics and radio projects. You start from one of 21 presets, such as a Raspberry Pi 3B, 4B or 5, a Pi Zero or Pico, an Arduino Uno or Mega, a Heltec WiFi LoRa 32 V3, a LILYGO T-Beam, a Seeed XIAO, an ESP32 Cheap Yellow Display or an RTL-SDR dongle, or you type in your own size and wall thickness. The body can be a box, cylinder, hexagon, octagon, pill or sloped desktop wedge.

Lids close with a friction lip, screw bosses for M2 to M4 heat-set inserts or self-tapping screws, a snap fit, a sliding rail or, on cylinder bodies, a quarter-turn bayonet. You then pick parts from a side palette and click a wall to place them: SMA and BNC antenna ports, USB, HDMI, RJ45 and DC jacks, PG cable glands, fans from 20 to 120 mm, vent panels, mounting flanges and PCB standoffs. A gasket channel is available for outdoor builds, and a side panel estimates filament weight and print time and lists the screws and inserts you need.

It runs fully in the browser with no account, and the source is public on GitHub, though without a license file. It is a young project from one developer, labeled beta as of September 2026, with a lot of settings, so it suits LoRa, Meshtastic and IoT builders who are happy to print a test fit first.

What you can make

Raspberry Pi and Arduino cases
LoRa radio enclosures
RTL-SDR dongle cases
Outdoor node boxes with a gasket channel
Round, hexagonal and wedge-shaped project boxes

How to use Faraday Enclosure Generator

Open the site and pick a board preset, or set the case size by hand
Choose the body shape, corner style and lid type
Pick connectors, vents or fans from the left palette and click a wall in the 3D view to place them
Check the weight, print time and screw list in the side panel
Click Export for a ZIP of STL parts, or download the 3MF from the same dialog, then slice the base and lid

Faraday Enclosure Generator pros

21 starting presets for popular Pi, Arduino, ESP32, LoRa and SDR boards
Wide lid choice, from snap fit and screw bosses to a slide rail and a bayonet
Shows filament weight, print time and a screw and insert list, and the STL ZIP includes a bill of materials

Faraday Enclosure Generator cons

Beta software (as of September 2026) from a single developer, with almost no community feedback
Many options and a click-to-place wall editor take a while to learn
Preset sizes are starting points, so you need to check them against your own hardware
