ThrowYo yo-yo by PaperScarecrow

Finally had some luck in designing and printing a yoyo. Uses a standard C size bearing and O-rings instead of silicone response pads, also requires a 4mm x 12mm threaded axle.
Make sure you thread in the axle straight, otherwise you'll get a lot of vibration.
I have a new version up now, it's marked as Rev1 in the files section. The major differences are that the new version has a larger diameter (58.5mm vs the original's 56.3mm) and is about 2mm wider. The cups are deeper to give it more rim weight and the axle system was overhauled to use an m3 x 16mm bolt and an m3 nut to prevent a stripping issue that could occur on the original version after it was taken apart for o-ring replacement or a bearing swap. Both the nut and the m3 bolt will need to be hammered (or pressed) into the body, but after they're both in it should be able to be broken down like a normal yoyo (you can use nylock nuts, but they'll make it harder to break down).
You can find C sized bearings and threaded axles at most online yoyo shops, as well as on ebay (I'd search for m3 x 20 threaded rod). This unit works best if you do a silicone response pad (search for flowable silicone response pad on google, you'll find tutorials) and use a concave or CT bearing designed specifically for yoyos. Yoyobestbuy is the best place to find these, just search for Buddha whipple or ripple bearings, they're about $5 a piece and last forever.
