Summary

So I printed LoboCNC's Roly Poly Quarter Fidget and was so impressed that I wanted to try something bigger. Slapped this together in tinkercad. It's not as pretty as Lobo's, but it's still a quick little print and it'll mate two hard drive platters (I'm using 95mm platters that are 1.22mm thick).

The tinkercad is here if you want to change the platter sizes to match other platters. A quick check of several of the ones I had laying around gave some pretty substantial differences in thickness.
