I have now developed a totally functional 3d printed version of the Dual Throttle, available for beta testing, as I ensure universal fit and function.
These can be purchased through Etsy, to provide easy and trustworthy shipping and payment features. As well as quantity management, expected shipping dates, and other order processing features.
Please keep in mind these are still prototypes, and the design can change at any time for a better user experience and more universal fit.
Use at your own risk, and ensure proper fit and installation.
