685 bearing flat cap

I liked the original’s idea of the cuts to get a bit of holding force, and that you had a customizer.
Unfortunately, when i typed in that i wanted a “685” bearing, i didn’t get an error message, but the default, a 608 bearing.
Turns out, there were no 11 mm ⌀ bearings in the list.

So i added an entry for the 5 mm × 11 mm × 5 mm bearing as “685”.
I also fixed it so you really get 10 bearings when you set that, not 12.
(But it looks like it’s not working for quantity 1. Oops.)

The coin (⌀ 16.25 mm) and SD card adaptor (24 mm × 32 mm) are there for scale.
