smoothie bottle cap container (e.g. pill box), 3 sizes

I recently made a standard bottle cap container and I had some smoothie bottles, so I wanted to make a bigger bottle cap container for those. 

There are standards for various bottle caps, and all 3 smoothie brands I tried follow the standard PCF-38P-1, which this container is designed for. That means there's a good chance it will fit yours, too - but there are other standards, too, and those standards are voluntary, so YMMV. If your cap's inside thread diameter is about 35.7mm and the thread has two starts it may be worth a try.

Edit: After making a bigger standard bottle cap container I also added a bigger version with knurling for smoothie caps, too - it turned out quite nicely I think.

Edit: …and I stumbled across another smoothie cap style, the “38mm 3 starts” (Bericap). So I made models for these, too. You can identify them by, well, them having 3 thread starts and 38mm diameter (that is the bottle's threads' outer diameter though).

Printing: I used a 0.4mm nozzle, 0.2mm layer height, PLA
