⚠ DISCLAIMER. I technically don't have permissions to post this, but I also had no way to contact to OP to ask permission to remix it since they Use MakerWorld and has a "Lv7 comment disturbance block" set making it nigh impossible for me, a non-Bambu user to reach out. IF YOU ARE THE ORIGINAL CREATOR OF THIS DESIGN, PLEASE REACH OUT OR LEAVE A COMMENT ON THIS DESIGN and I will gladly work with you if there is an issue. ⚠

About the design

I've really been getting back into wardriving lately and noticed a serious lack of Seed Studio Xiao ESP32-C5 cases out there. However, I did find a really great ESP32-C6 design and decided to adapt it. So far, I've been really happy with it and found it could be extended quite easily.

A quick note about linking your Xiaos: you technically only need to link the 5v and GND. I didn't know that at first so please ignore that the photo of the 3x version has 3 wires. 😅

Printing considerations

If you plan to leave this in a car or any place that might get hot, be sure to use filament that can handle the heat. I finally settled on PCCF. Admittedly, my PCCF print did warp a little bit, but once I snapped the 2 halves together it flattened out nicely.

FAQ

• Which antennas did you use?

  • I used the antennas from Seeed Studio: 2.4GHz 2.81dBi Antenna for XIAO ESP32C3 - Seeed Studio

• How long are the SMA connectors?

  • Measured from the hex base of the adapter to the end of the IPEX/UFL connector, the ones I used were 70 mm. That said, my measurements make me think you could go as short as 16 mm.
