grabcad

Simple pop bottle cap for when you need to add something to a pop bottle like an inlet or two, a pet watering system or when you want to make a bottle rocket. Uses (mostly) the PC01881 sizes (ID25mm, OD 27.4mm and thread pitch is 2.7mm). Designed for 3D printing so the thread OD is slightly larger at 27.7mmIf you're printing this, be aware that printed parts are porous and if you need it to be air or watertight it needs to be sealed with something like nail varnish, polyutethane varnish or a paint
