Strapped some lasers and lights on our dropcam and drifted along the Santa Monica Bay ocean floor at about 40m depth. Absolutely hacky, but it worked.
Plenty of brittlestars, sanddabs, urchins, tubeworms, anemones, and more!
Turns out octopuses are a lot like cats when it comes to lasers.

Two tries later: success!
Increased fill to 60% and used a rectilinear infill pattern. Printed with a Bambu Lab A1 printer. Took 10:47 to print.
This one liter sediment core weighs 179g, has a beveled top edge, a 1-mm screen on the bottom, and is just slightly *negatively* buoyant.
It’s perfect.

As we replace old and damaged gear, why not use newer/cheaper/better technology?
I designed and 3D printed a diver sediment core with 1-mm screen and a beveled edge.
Not bad for a first try, screen isn’t perfect but it’ll work.
Biggest issue? It floats 😳🫠🤷🏻♂️ Guess I need a higher infill %?

I’m in the middle of family leave, but I took two days back because some students told me they wanted to test out a promising project.
Lo and behold, three automatic (via thruster and pre-programming) CTDs that we made race through a profile program.
The red one won! 😂
