About

Rotational Inertia yoyo's is geared toward advancing the production of 3d printed yoyos. This process will include making, scanning certain parts, and fine tuning the yoyo. The yoyo prototype I am designing is made in TinkerCad, an online CAD program by Autodesk. For the shape, I decided to go with a basic H shape, with a V drop. An H shape is good because it has higher rim weight so it spins longer so you can do more tricks. It has a wider catch zone and a projection flare.The project picture is the model I am working on, almost done shaping the edges, and then to fine tuning it to my liking. For CAD experience I have been learning SolidWorks for over a year and have been using tinker cad to make an upload things to Thingiverse. I already have a printed prototype and the bearing seat is fine ( not final yoyo, won't picture because it's horrendous). I plan on using flowable silicon response and a 10 ball C sized bearing. I am trying to get 2 printers and I can run up to 2 halves on each machine at the same time and it takes 2 hours to print 1. All the surfaces of the yoyos will be sanded. As for the exact weight, it is yet to be determined, and I have a second prototype of this same yoyo underway. These will be printed with PLA and ABS depending on what the customer wants.
