The Last Spinner Cap (with concave)

thingiverse

I'm absolutely thrilled with Zigian's "The Last Spinner Cap" - it fits like a glove and grips the bearing flawlessly. However, I must admit that my ideal cap has a concave cup to cradle my finger or thumb in place. To achieve this, I took Zigian's 22mm wide "tall" cap and gave it a subtle makeover by adding an outer ridge and an inner concave curve. The result is a Finger Spin cap that's tailor-made for me. I've since taken things to the next level by crafting an even better model - one that's slightly taller, providing a deeper cup for my finger to rest in. Both caps work beautifully, so it ultimately comes down to personal preference.
