Made some revisions to this design, for now it’s called the “Two Step”. Most of the changes are inside the cup - the indentations have angles instead of steep walls, and the rim has more work done to it. ![TwoStep%20Cup](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/2/c/b/2cb3d5e2f722ddeee16d1f70fe26a384a6ff3c4b.jpeg) The catch-zone area of the rim has a lot of options, though. I added an indented ring where it transitions from inverse to round, similar to designs like the CLYW Compass. I also had some ideas for the round part. Here there is a round part, with a flat part right near the edge. ![Some%20Angles](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/2/d/b/2dbaa450b90a74f0446dc926b687185b5d40abe0.jpeg) This version is fully round. It’s simple, at least? ![No%20Angles](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/5/5/7/557254054c4e15ece808c1ae7d8c7c5751a55929.jpeg) This version is all angles! It’s probably a bit too much. I had been playing with an UNPRLD Abduction all day. ![All%20Angles](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/a/7/6/a76e1068754fe68625077b3b3f085a36d0890a6d.jpeg) All of these are around 63.5g assembled, 46mm width, 56mm diameter, 8mm axle. The body material is 7075 Aluminum. I feel like I want to make 100 tweaks before I get this prototyped (just a one-off run). ---

Here is another yoyo I started making. I had the intention of making a fun O shaped yoyo, but it evolved to try to become a little more competition friendly.

I like the middle shape best. It has nice curves and looks the most appealing. The other two are just a little too angular, but that is just my opinion ---

The gap round one reminds me a bit of the silenus/meta shape: ![Silenus](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/2/c/a/2ca7f03c60bb71b9b7b749ebd90d2f78ff546b93.png) I think it might make sense in yours to smooth out the transition from the response bump to the inverse-round section, it really sticks out to me. The cup looks decent, though if you’re going to have an axle nub I think it’s worth trying to really make it really special/unique. ---

Do you like the little ridge-cut between the curved parts? It used to be just a sharp corner, but I’ve seen this little cut on a LOT of yoyos and it looks pretty nice imo ---

I rounded off the transition. And how dare you insult my axle nub. I have zero creativity.:joy: I see what you mean, but that has always been my favorite kind of axle nub.

FPM quoted me ~$450 shipped for 5x of one of my designs in 7075. Additional quantities are cheaper per piece but not by a whole lot for prototype-sized amounts. They’re apparently one of the top yoyo machinists in the world - look up the Yoyofriends Hummingbird and Magpie for examples of their in-house designs.

Quite a while ago I jumped into the design field myself. I watched that same video by Zach Lerner, and designed a yoyo with no further knowledge. here I present: “The Exponent” ![yoyo_cut](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/7/6/2/762f0503809c84afa676f1a58c6a2545cd6d1d45.jpeg) ![yoyo_profile](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/e/1/1/e1118d8a03be3fb3230d78f56fe43ad0cb7ba326.jpeg) ![yoyo_side](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/a/2/5/a256ff766f82450085b5ee40b2612e300f35bc55.jpeg) ![yoyo](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/2/d/f/2df64212752b35b13cf9c60b3597a9fb47f2b311.jpeg) ### Specs Diameter : 55mm Width : 45mm Mass : 64g Material : AI 7075 Axle : 10mm M4-0.7 : This yoyo draws great inspiration from popular designs like the G2 Banshee, YYF ND etc. The Exponent plays very stable and floaty, With a wide shape for great catchability. I started with the design of a Banshee. I’ve always felt the final production banshee was too slim, and to large in diameter, so I streached the outer rims making the profile wider and the rims much thicker, giving it a more “solid” feel. And I shrunk the diameter by a little more than 1mm, for my love of under/midsized yoyos. Next, I lowered the walls next to the response, because I have a somewhat aggressive playstyle, that makes higher walled yoyos tilt unintentionally. I also make the response size more standard to further reduce tilt, and make response options more open. with **a-lot** of fine tuning I got a yoyo I was in love with. It was truly something of my own. If you would like to try it. I go to the spindoctors yoyo club almost every month. you can find more info here : > **[Spin Doctors Yo-Yo Club](https://yoyo.fandom.com/wiki/Spin_Doctors_Yo-Yo_Club)** > > The Spin Doctors Yo-Yo Club A.K.A. "Spindox", out of the San Francisco Bay Area in Alameda, CA, achieved world notoriety for cutting edge tricks and great players.

A new design of mine. It has a press fit steel hub to prevent the axle from stripping.

That shape is really cool. It reminds me of the YYF Marco. from the looks of that press fit hub. it isn’t connected to the cup in any way. meaning when the yoyo is assembled you can pull on the cups and they would pop right off. (the hubs, bearing, and axle would stay together) you wouldn’t want that to happen when it is spinning. ---
