Design your own bottle caps and necks so you can create custom containers that fit your exact needs
Works with standard water, soda, and juice bottle caps so you skip buying special hardware
Includes three common PET bottle thread sizes so you have options for different projects
Use for pet water dispensers, plant watering systems, and bottle connectors so one design does many jobs

Build your own custom bottles and containers. With this design file, you create necks and caps that match standard bottle closures you already have at home.

The file gives you three popular thread sizes: 28 mm pco 1810 for classic water bottles, 28 mm pco 1881 for modern sodas, and 38 mm for juice and flat beverage bottles. This means you work with caps from bottles you use every day, not special parts you have to buy.

Pet owners use these for water dispensers. Gardeners use them for plant watering systems. Makers use them to connect bottles together. You get one flexible design that adapts to what you need.
