This 3D model is the case for my self-built smartwatch with ESP32-C3 Zero. The design is available in two different sizes:

  • 👨🦱 Adults: Wristband length approx. 22 cm
  • 🧒 Teenagers: Wristband length approx. 20 cm

The case was printed with a 0.2 mm nozzle to achieve a particularly clean and precise surface. I recommend printing with PLA or PETG, 0.12–0.16 mm layer height, and at least 20% infill.

🧩 Suitable for:

  • ESP32-C3 Zero Board
  • Round TFT display
  • TP4056 charging module
  • 500 mAh Li-Ion battery
  • Buzzer, buttons, switches, and brass threaded inserts (Heat Inserts)

💡 Tip: The brass threaded inserts can be carefully melted into the case with a soldering iron.

This design is part of my DIY Smartwatch Project with many functions such as weather display, world clock, games, battery display, and smart home control.

Additional notes on printing and usage: I kindly ask you to always print the model with the integrated logo – this is a must to preserve the design as intended. I also highly recommend it, as it makes the case visually more beautiful and authentic. For private use, usage is of course permitted and welcome. Commercial use, however, is unfortunately not allowed to maintain the integrity of the project. Please do not share the files; instead, feel free to refer to my Makerworld entry or my links. If you share the project on YouTube or social media, that's absolutely fine – I'm even happy about it! – but please link me so others can find the origin. Thank you for your understanding and support! 😊
