I’ve been messing around with Sketchup today and ended up making a yo. It’d be sweet if it was made, but those are just high hopes. 
Its got a 52mm Diameter and would have about a 40-ish width if put together.
That looks so smooth, it has a huge gap, that be so easy to catch strings in, in like really hard tricks, if this got made I would certainly buy it, are you able to add colour, if so try splashing it, or have it red.
It’s like a mutated Catch 22 / C13 / Frantic!
I’ve been messing with it and Alibre is what I got. Now just to find a machining shop…
That would be so sick if you could machine that. What would you call it? (when I see it I think StingRay)
That is sooo cool!!! :o
Almost looks like a bell…
Kind of a short bell, I hadn’t seen that.
I have no idea what I would call to be honest. Maybe I could make a company and have it all under water names. 
But the StingRay isn’t too bad…
If you machine it, I’d definitely buy one from you! Love the sharp rims! Nice and original. 
:o :o :o :o :o :o :o That is really cool. It is also very original.
