VW Mk1 Injector Cup Removal Tool

thingiverse

I couldn't find an allen wrench big enough in my tool set, so I just printed a hexagonal prism long enough to get a socket on it. Worked well for me with an 11mm socket. Let me know how this works for you. I printed it laying on it's side so the layers are oriented along it's length. I didn't need supports, but I'm the king of overhang printing, so do what comes natural for your situation.
