A one-off, custom diffuser wrench sounds pretty cool.
Build one.
I tried to take one of my Vertex fusers apart after Cecil mentioned the trouble he had the first time quite a while ago. Nope, need a tool, and these are brand new.
I was thinking of building a fixture out of wood to nest it in upside down (membrane on the bottom), then build a T handled gizmo that has positive pilots to engage the bottom webbing/reinforcements (whatever you want to call them) so you don't slip.
Then I thought, if they ever get that dirty, and can't flex clean them, I'll just buy new ones. The wastewater versions are much cheaper than Vertex anyway, and make them in many more flavors.
