Support the Creator: Defending Thingiverse Cube!
I need your support. My "bakercube" became the most downloaded object on Thingiverse for an incredible 16 months, with over 158K of you printing it at home (Sep 26, 2019, web.archive.org) within the first 2 years. I'm truly grateful for the overwhelming response and the sense of community we've built.
However, two lawyers operating under KitchenCube LLC and Altamatic LLC used my cube design without any authorization, manufactured it in China, and are now selling the derivative copy of the cube on the market. This is a blatant violation of the Creative Commons, non-commercial, no derivative license we use here with our work.
When I confronted them, they told me to go away and threatened legal action against me. I believe in standing up for creator's rights, and I refuse to let our hard work be exploited in this manner.
I am seeking your support in raising funds to cover legal fees and expenses to bring our authentic version of the cube to the market. Please consider contributing and sharing the link:

The Tesla Valve is the brilliant design of Tesla himself, sculpting the flow of water to allow it to pass unrestricted in one direction, and restricting the flow in the opposite direction.
Tesla valves are commonly used as micro-valves. The theory behind this invention is quite complicated, and often subject to scientific papers describing fluid dynamics.
In this toy, there are two Tesla valves side-by-side: one in the unrestricted and the second one in the restricted directions, so you can observe an amazing geometry of this invention.
Tesla valves work when they are covered, so you can put the cover on and see the difference in the flow output by measuring the volume of the escaping water. Please note that in this specific application we are using only 4 segments (Tesla patent used 11), so the “performance” of this toy is much lower than in an actual mechanical application.
You can fit the entire assembly (with a cover) onto your kitchen sink to see the difference in performance on both sides of the valve. Tesla Valves performance improves dramatically when using the oscillating flow (on-off-on-off), like in oscillating pumps.
