Water Resistant Project Box with TPU Seals

Keep your projects neat, tidy, and protected with this maker-friendly project box! Designed for 3D printing using a dual nozzle printer, this enclosure features 42mmx81mm internal dimensions just the right size for small electronics, sensor modules, or microcontroller builds.

The main shell prints in sturdy PLA, while the TPU-based lid seal gives it a satisfying snap fit and a light dust-/moisture-resistant barrier. For extra versatility, the side panels are also printed in TPU, so you can easily drill or poke through for clean wire entry and exit without cracking or splitting.

Ideal for ESP32/ESP8266 projects, sensors, IoT gadgets, or any compact circuit you want to keep protected and professional-looking.
