How does one get the design software? Looks like it's called "CloudDDM App" but not to be found on site...
When loading part to CloudDDM, you simply send a .STL file that is provided by your CAD software and it quotes it. I shared my .STL file from the horn button a few post ago. I think they are running a promotion right now. I think you can get a free part made and shipped to your door.
