Customizable Homebrewing Sugar Spoon
thingiverse
For adding priming sugar directly to the bottle, I needed a measuring spoon where I could define the amount of sugar in grams, so I modified the original double ended measuring spoon by visaviz to calculate the volume/radius from the required sugar weight. The stl file measures 1.6g on one side and 2.4g on the other one, a reasonable amount for 0.33l and 0.5l bottles. To be exact, use a priming sugar calculator and customize this thing for the amount of sugar you really need.
