Quickly measure the right amount of tea leaves for one pot, or other granular materials where you need the same amount every day:
It works reasonably well one handed.
This is the second design for this purpose. I renamed the first one to old tea portioner.
The stand is not strictly required, but useful to keep the bottom of the portioner clean, and, depending on the sizes, to stabilize it a bit.
There are STL files for a number of sizes. 47 cm³ and 66 cm³ are the right amount of rooibos tea for my two teapots, 1 dm³ and 1.4 dm³. For other sizes you should use the customizer, or (when it is not working) download the scad file, load it into OpenSCAD on your computer,set the volume and generate the three parts there. When you have a mass, look up the density in the FAO list, elsewhere, or measure yourself. Americans should look up the millilitres per teaspoon &c. in this list, and visit metric4us at their leisure after they printed their portioner.
As a reminder to everybody, millilitre and ml are just synonyms for cubic centimeter and cm³, as are litre, l, L or ℓ for cubic decimeter and dm³.
While i prefer this style, where you pour the tea, especially when you’re almost out of tea, there is, of course nothing wrong with using measuring spoons or scoops like things 682146 or 619626. Except from the use of lots of useless units, like two “fl.oz.”. That there are different fluid ounces is one of the many, big problems with non-SI units. Anyway, for both you should just use 30 cm³ instead. (When you need precision, you should use a graduated cylinder.)
The customizer works now, after i removed every non-ASCII character from its input.
