2,5 g salt spoon for nasal irrigator

Since I have some problems breathing through the nose, I'm trying nasal irrigation at the moment. Not the most pleasurable experience for me … but if it helps in the long run, well … 😅

One should use saline water of the right concentration - approx. 2,5 g of pure salt (no iodine or other stuff added) to a 250 ml fill of lukewarm water. I found a round measuring spoon here on Printables, but could't get the overhangs to print despite having decent cooling. So I quickly designed my own overhang-free spoon.
