Xterra DS2 (Design Study 2). A 1 of 1 project based on the Triple Zero body. Over 300 hours in CAD alone have been done to create this yoyo (this was before generative cad was widely available).
The yoyo and stand is made from billet machined titanium, and the plastic parts are resin 3d printed with "Luftverk" logos on both.
The cost for this project was just shy of $5700 due to the fact that I ordered a full production run of 25 units, with stands machined not including the 3d printing, or my time spent on it. I canceled this project shortly after receiving the parts. So if I sell it for asking price Ill still be loosing $2150. I don't really recommend you buying it unless you really think its worth it, but thought id put it up here as an example on how not to run a business.
Its also not smooth. Its a display piece.
Smoothness: 7/10
