DIY 3D-Printed Mini Storage Containers Threaded for Existing Bottlecaps
Thingiverse denizens have been 3D printing these tiny, nifty storage containers, threaded to match bottlecaps on common products.
They come in three variants: Normal, knurled and slitted.
The .stl files were created by Japan-based Thingiverse user Tokyo Bird and are available here, though I’m not sure if Japanese-market bottlecaps are threaded to the same dimensions as the ones in the ‘States.
