While I find the intention here noble, I want offer a perspective and touch on the industry implications of such a project. Your stated aim to get everyone what you believe to be the greatest yoyo ever could in fact be damaging your chances of something better being created.
It’s great to be able for everyone to get great cheap ti yoyos or great any yoyos for that matter. Any action however will have a reaction and here I see the creation of what is essentially a shadow in the market. In this Shadow nothing grows. You will see a decrease potential innovation and future design progress. Small yoyo makers, like the one whose design you are emulating will not have the ability to produce and publish designs until the glut of yoyos and the inevitable resale market for them dissipates. It creates a hostile environment and the environment is tough enough. Ti yoyos have a perceived price. That price is already low by industry standards with margins already very low. Any scale manufacturer will find no lower return on investment than making Ti yoyos . The price expectations were already built on small manufacturers (and even retailers) accepting a lower margin on ‘marquee’ items. For this reason there are periods in time no Ti yoyos were available retail. We have been guilty of this. Ti Dream was only like 3 years ago. There were no full sized titanium yoyos available consistently and we didn’t price high enough to grow a sustainable market. However within 6 months of release there were 5 or 6 more titanium yoyos in the market so we didn’t scorch the earth too bad.
I might totally wrong, and I could totally make an argument this could be enough to push people past titanium and we could finally get the next step in innovation as a result of this. Anyway it was a thought that was rattling around in my head I thought worthy of adding to the conversation.
Separately, i wanted to offer a cautionary tale when producing any titanium yoyos in quantity. Tool wear is vicious and it is hard to create many identical parts. Even your vendor had some issues with numbered yoyo releases I believe? We did with Ti dream. 3rd party fulfillment without a final qc inspection on every piece is a risk.
