Spanner for 50mm basin nut

I had to change the sink waste on my bathroom basin and couldn't get the adjustable pliers in to get a good grip, so I made this. Worked a treat. It seems a bit flimsy when printed but the nut gives it rigidity. Needs supports. I've attached both the .stl and .step if you want to modify it. I used PETG but I expect most materials would work.
