Finding a right nozzle for my watering can wasn’t easy. I ordered one online, but it didn’t fit.
A few years passed since then and the can didn’t work in the meantime. Recently I had the idea to print my own.
The print took about 8,5h – my longest print ever.
The nozzle fits on diameters of: x: ~25mm, y: ~28mm
