Any tips for repairing Mark Audio MAOP :(

I'm fuming with myself.
During a cabinet tweek which involved removing the drivers, I've dropped one of the screws on the dust cover and it's dented it.
I'm sure this has been discussed before, at length I imagine, but these drivers are new territory for me. I don't fully understand what they're made of and how heat etc will affect them.
So far, I've superglued an o ring to a plastic straw and used this to try and suck it out. Nope.
I could use more power by attaching the hoover hose to the straw?
I've tried a piece of Blu Tak and a swift yank. Nope.
🙁
Any other ideas.
