This is a basic rehash of a bead dispenser for 3mm glass beads. These are used in the process of manufacturing COVID-19 tests. Follow the Prusa sanitization guidelines here to ensure that these remain clean for laboratory use: https://help.prusa3d.com/en/article/prusa-face-shield-disinfection_125457#ga=2.217385878.1262986892.1587172476-1581692016.1557082179 Beyond the 3 printed parts you will need 8x M3 screws about 16-18mm long and 8x M3 nuts to hold the pieces together. I have included the Fusion 360 assembly file to make it easy to see how they fit together, but it is pretty straightforward. Hopefully you can find this useful.
