Someone from a Wanhao Facebook group I'm in was looking for a fidget toy in this style. If it's a little tight just try again at 102% or something like that. This size has worked great for me on the rest of my designs though. The printed picture is fresh off the printer, running at 70mm/s. Would look better if I slowed down a bit.
V2: I made V2 a little bigger in the outer diameter. V1 is fine, it was just a bit small.
Note: Someone commented about a problem with V2, so I removed it until I had a minute to look into it.
