USS Enterprise NCC-YOYO-D

Space: the final frontier. These are the voyages of the yoyo Enterprise. Its five-year mission: to explore strange new skill toys; to seek out new throws and new tricks; to boldly yo where no man has yo'd before. 

It uses a 4mm x 20mm stainless steel shelf pin as the axle. These are the ones I used. https://www.amazon.com/gp/product/B0D1VF3P4C I recommend a tiny drop of super glue in the axle hole then the pin, then the other half with glue as well. Print at 100% infill or it may not work. If you print it and it doesn't come back up add a drop of lube or rub some chapstick on the end of your string and after a couple throws it will work just right. 

There are two stand models, I would start with the smaller model and use it unless you yours doesn't fit, then print out the larger one. 

It also functions as a mediocre spin top if you get bored with yoyoing.
