Waverunner water plug key

I have a 2021 Yamaha waverunner that has water plugs in a bad spot to get a wrench or plyers on them. So this design grips the very short handle and lets me twist from further back. The slots at the opposite ends would let me use a flat head screwdriver and the holes would let me slide a small bar for twisting.

I printed with 12 walls and 85% infill for strength. It may be overkill. I used supports but only for overhangs over 50 degrees, that excluded the holes.

I printed standing up, with the X on top.

I designed a short and long version. the area is further back, so a longer one may be more useful.
I designed the edged version so I could get plyers additional grip if needed.

I designed in Tinkercad. let me know if you use this and how it works. also if there's any suggested edits. I'm thinking about a T-handle version or one with a slimmer shaft.
