Originally designed for our research team to sterilely collect water and sediment samples from within storm drain basins, this 3D-print assembly can be fastened to the end of a sampling pole or paint pole to allow for easy sample collection via a 50mL centrifuge tube. This has been really helpful in collecting different kinds of environmental media from hard to reach places, check it out and share with a fellow environmental researcher - thingiverse.com/thing:6884677!
