This is a very simple design for a 1 cc scoop for measuring the bulk density of powders. It is useful for the Don't Judge a Powder portion of the middle school and high school Science Olympiad competitions. It probably also has some use in generic science courses. The interior of the scoop is 10mm x 10mm x 10mm which of course is one cubic centimeter and also one milliliter. To calculate a bulk density, tare the scoop, fill it to the top with a powder and then reweigh it (in grams). The mass you measure is the bulk density in grams/cubic centimeter.

Unless you have a very good printer, these probably aren't water tight, but they work well for powders.
Download and print. This design does not need any support although there is a 10 mm bridge which is helped with some cooling (V2 doesn't need any bridging). It shouldn't be too hard.
