Access to the basin nut is often difficult. With this tool the nut can normally be tightened or loosened by hand, but if needs be waterpump pliers can also grip it a lot easier than directly onto the actual nut.

2 sizes are included (to match my fittings in UK) but any other size can be created by scaling the model equally in X&Y.

test files print a 3mm section to confirm a good fit before committing to a 2 hour print.
