The Suonare knob has a sinusoidal curve of bar graphs wrapped around the body. I unfortunately can't get the renderer on Fusion 360 to work correctly, or rather, I don't have the time. Twin dad and all.
Anyway, it should be a fairly easy make. I haven't had the time to test it out, I will when I can but I might not be able to before the contest closes its entrants. I plan on giving it the treatment of my Fanook models, with drawing and photo once done.
To get the full effect you should probably download and color the components, then rotate it to see what I'm going for. I would've loved to develop the idea further, but as I said, twin dad.
The author marked this model as their own original creation.
