Have you got a plastic bottles lying around your house, and you are just about to throw them away? Well, this will be a perfect small project for you to do.
If your 3D printer is bigger enough to print the whole thing then you can go a head and print "watering_can.stl". However, if your 3D printer is too small to print the whole thing, then you can print "watering_can_1.stl" and "watering_can_1.stl". Enjoy!!
