Drew this up because I needed to water some plants around the house while we were on vacation. These are designed to have a taper to fit most common soft drink and water bottles. Simply print this, then heat the neck of your bottle slightly with a water and press fit it onto the adapter.
I didn't use threads, as I wasn't sure if they were all the same across the different cap designs.
Nozzle2.5 is a 2.5mm orifice, which seems to make a small bottle like the one shown in the photos last about 3 days in 85-90deg. weather. Nozzle3.5 is a 3.5mm orifice for a little greater flow for larger plants.
These are designed to print support and brim/raft free for quick and simple printing.
