Phrozen Mega S Wash - Drain Nut Holder

My Phrozen Megas was leaking around the washer of the drain tap. I tried tightening it, but found it just spun. I had no tools which could fit in the small slot available, so I opted to make a little holder that stops the inner nut from rotating whilst you loosen/tighten from the outside. My first Thiniverse upload, so hopefully it's ok.

As to slicing, I think PLA works fine, but maybe PETG is better. I'd suggest a decent wall count, 3 or 4 maybe, and 25% Gyro infill unless you have something better.
