Outdoor Extension Cord Box – Weatherproof Case

Outdoor Extension Cord Box – Keep Your Power Connections Safe from Rain and Snow!

Need to safely extend a power cord outdoors? This weather-resistant enclosure is the perfect solution to protect your plug connections from rain, snow, and splashes. Whether you’re setting up garden lights, outdoor tools, or seasonal decorations, this box keeps your cables dry and secure.

The design features two interlocking shells with a precise fit and four snap latches for quick, reliable closure. For added safety, you can screw the parts together using four M3x30mm screws — and seal the holes with TPU caps whether or not you use the screws.

Note: to use the screws, you’ll also need to insert 4 metal heat-set threads (M3) using a soldering iron.

Inside, the 60mm diameter fits even bulky adapters like Schuko plugs. It also includes three interchangeable TPU grommets (4mm, 6mm, and 8mm) to match your cable size and keep things sealed up tight.

✅ No supports needed (except screw holes)

✅ Fast and easy print

✅ Recommended materials: PETG, ABS, ASA for the shell – TPU for grommets and caps

Stay powered up, rain or shine – and happy printing!
