I can't get the top cap off my Maker. Won't budge. Any suggestions?
With my hands, I run into situations like that often

I finally cut a small rectangular piece of that bumpy rubber-ish cupboard liner.
I wrap that around it, and PULL (Nuppins).... but it has to be attached to a mod.
It works pretty good for me, as it doubles my grip.
But, I have to attach it to a mod, or ohm tester to pull it off.... that's the key to getting it separated.
There's NO WAY I can hang onto that little screw part, and pull it apart

Hope it works for you too
