Mini Container with PET Bottle Cap - 3D Printed Organizer

This mini screw-cap container is one of those cool 3d printed things that solves a dozen small storage problems at once. Designed to fit standard PET bottle caps, you can customize the look by swapping in any cap you have on hand—or print the included cap in your choice of finish.

Choose from three cap styles to match your needs: a smooth normal type, a slit version with a 1mm opening for dispensing, or a knurled design for extra grip. The compact size (30mm outer diameter, 23mm inner) makes it perfect for organizing tiny essentials like silica gel packets, small hardware, or even 608ZZ bearings—it holds exactly four.

Whether you're building out tool organization for your workshop or just need a clever way to store pills and pocket items, this versatile little container delivers. The threaded design ensures a tight seal, and the modular cap system means you can mix and match styles across multiple containers.
