Sensors

A case for your C5 field kit.

Print a home for one, two or three XIAO ESP32-C5 boards and their sticker antennas. Regular and MagSafe versions, photographed assembly, and downloadable 3MF projects.

The pictured build holds three boards in a single translucent enclosure. Each board keeps its own antenna and USB-C connection, with button access and visible LEDs through the cap.

Print-file revision: September 10, 2026. The featured download is the three-board MagSafe base and cap in one PETG project.

01 / Choose your enclosure

One, two or three boards.

The regular case has a solid antenna bay. MagSafe versions add a pocket for a magnet ring and a larger footprint. Use a matching base and cap from the same size, family and revision.

Paired PETG projects contain both pieces and Bambu Studio settings. Individual parts contain geometry only. For boards with pre-soldered header pins, substitute the matching base with through-holes.

Start with the fit coupon. This small USB-end sample lets you check the board seat, USB-C opening and snap fit before printing a full case. Download both the coupon base · 3MF and coupon cap · 3MF.

02 / Before you print

The five paired projects target a Bambu Lab X1 Carbon, 0.4 mm nozzle, textured PEI plate and PETG Basic. Check those choices against your printer and filament before slicing. The downloads are 3MF project or model files, not ready-to-run G-code.

Print the base floor-down and the cap top-face-down, as exported. The regular three-board variant has separate base and cap files; this release does not include a paired PETG project for that variant.

Existing geometry and slicer checks do not confirm the fit of every physical combination. Check the coupon, then test your assembled case for cable clearance, snap fit and button movement.

03 / Put it together

Keep the cables and controls clear.

  1. Dry-fit the antennas. Position the sticker antennas and cable loops around the visible support pillars before peeling the adhesive. Keep antenna film and cables off the tops of the pillars.
  2. Seat each XIAO. Route its antenna cable through the open channel, attach the antenna connector and place the board USB-C first. Confirm that a cable can seat fully.
  3. Use the matching cap. This revision pairs base pillars with short lid contact pads. Print both halves together; an older cap with long feet can collide with the pillars.
  4. Check the buttons. BOOT and RESET should move independently and return freely. Squeezing the closed case across the centre or cable area should not press either button.
  5. Power and connect. Flash each board with the ESP32-C5 installer, supply USB power to each board, and connect the sensors from WLAN Commander. See the connection guide for the app workflow.

For the MagSafe build: install the ring after printing and test its orientation against the intended phone or mount before gluing. The documented ring is 53.90 mm outside diameter, 45.80 mm inside diameter and 2.60 mm thick, with a 0.60 mm steel yoke. Metal behind an antenna can affect reception; compare your assembled layout with a regular case in the conditions you intend to use it.
