Borrow - eThirteen crank removal tool?

Maybe a long shot, but does anyone in Melbourne have an eThirteen crank removal tool?

Going riding Friday, was hoping to swap my cranks before then.

I used to have a pair (not sure what model) I recall their being some trick of removing crank bolts and flipping them or something to create an extractor?

Hmm ok, I’ll do some internet sleuthing and see.

I’m replacing them with a later model which has an inbuilt extractor like SRAM cranks. I removed that inbuilt one and tried to use it on the fitted cranks, but it didn’t thread in far enough.
