Beyblade spin gear remix

thingiverse

As I understand it, this is a spin gear for a "plastic gen" Beyblade. I redesigned based on the source in Fusion 360 to make it more printable, but then found out that I was probably wasting my time with that design. Oops. Well, here it is in case anyone needs it. I've also replaced the original tip design with a recess that will hold a 6mm airsoft bb, as I've had excellent results using those for some of my "normal" (not Beyblade) spinning top designs. Trying to understand how to print Beyblades as a part of getting my nephew interested in 3D printing. Found the original spin gear but the model was a little rough and I saw no good way to print it without a ton of supports which resulted in crappy surface finish. I really enjoy modeling in Fusion 360, so I decided to redesign it from scratch. I simplified the design as I think the source thing had been modeled to directly match an original Beyblade part which was no doubt created with injection molding. Injection molded parts have different design limitations than 3D printed parts, so I tried to keep the basic design intact but simplify it and make the piece more printable. I've got two renditions of the part - a single piece "Beyblade spin gear complete" which will require supports. I suggest printing it as-is so the surface finish of the exposed lower section will be better. Also, I found that the residual surface imperfections of the supports allowed me to file the surface until the weight disk and attack ring fit nice and tight. The other rendition is the part split into two pieces, the upper and lower sections. Neither should require supports, and then you can use a 2.5mm hex key in the center hole to align the pieces when you glue them together. Superglue seemed to work well for my model.
