I filed for a patent a couple days ago on the burr assembly, and a design patent on the wood arch thing, but definitely not looking to prevent anyone from making their own. Only to prevent some massive company from running off with it or even patenting it since I'm never going to be that high profile.
It is definitely true that larger burrs have more surface area to retain grounds. In general, I think most people consider the tradeoff worth it in terms of flavor, especially because in my experience the coffee that builds up in the burr of any grinder is likely to stay there whereas coffee that sits in nooks and crannies around the chute is likely to get cycled each time.
The knocker is actually hidden within the hopper itself, you twist and release it and it knocks into the burr. The basic idea for the design is that you have 3 rings, and each of them is a touch point, the bottom turns it on, the middle adjusts the size, and the top is the knocker.
Below is a great James Hoffman video comparing traditional coffee grinders to roller grinders, though the company keeps a lot of the details a secret, their grinder not only has a very long grind path, but also a dedicated densification stage.

I have only done blind taste tests using my friends and family as unwitting participants, and they've universally preferred turbina over a 64mm flat burr grinder with titanium nitride burrs and a high-ish end conical hand grinder. But obviously, this may be a matter of preference!
Argh, yeah squarespace seperates the store from the overall site. Definitely need to re-organize and add some stuff, like an about us page. For now, you can uhhh watch me fighting robots on TV
I used fusion to design and printed ergonomic/partial prototypes on Prusa 3d printers. Then, I fortunately had a ton of manufacturing contacts because I have worked as somewhat of a production engineer before. Some parts were definitely difficult, especially the outer burr of the grinder (there were a couple viable ways to make it, but it is sometimes difficult to find a shop that is price competitive in say wire EDM machining and 5 axis CNC, or CNC and casting, so you have to get shops to coordinate with eachother) or the wood arch (because high volume wood shops are not nearly as technologically sophisticated as metalworking shops)
PCBway is a good option now, especially for 3D printed metal parts. They have CNC as well but they tend to struggle with anything that has complicated geometry or features. But 3D printing doesn't require approval, and for one offs is often cheaper.
But absolutely, going to add more "banana for scale" photos asap
