[Hopefully] Dripless Watering Can
While searching for a small watering can, I didn't find what I was looking for, so why not add another version to the available mix.
Dripless Pouring
Because I stumbled upon an interesting video and article on the teapot effect before, applying this principle to a watering can also doesn't seem to hurt. According to a paper with the bulky title Wetting Controls Separation of Inertial Flows from Solid Surfaces, designing a sharp-edged spout can help prevent dribbling.
So, this is how it's designed to cover the edge curvature aspect, at least. Higher pouring velocities and low surface wettability also help. Yet I am unsure whether PLA or other materials would be the best match.
Details & Capacity
The can in its original size holds about 400 ml (or grams) of water when almost completely filled. Its wall thickness is 2 mm because I am anxious regarding thinner walls and waterproofness.
The model in the picture was printed in Bambu Lab Oxide Green Metallic PLA with 0.2 mm layer height and without supports. Designed in Plasticity. I am using the can together with this self-watering planter.
Happy watering!
