Today, Microsoft has released 3D printable design files for 4 different yo-yos. The collection which is available now on Thingiverse allows you to 3D print and then assemble your very own yo-yos at home. It should be interesting to see how well these actually work and which infill levels work the best. Are any of you going to print these? We'd love to see your results. Post them here!
