mostly notes for now...work in progress
When rearing fish larvae in a regular aquarium, many factors reduce their growth and, ultimately, survival. In addition, it's hard to monitor the larvae when they can spread out and hide, but I wanted to be able to inspect them under a microscope during the first two weeks while still having them in beneficial flow-through conditions with well aerated water.
Commercial rearing cages do exist but are quite expensive (I need 10-20!) and have the wrong dimensions for my use case in the laboratory.
Acrylic Glass Tube
- snap-fit ring to hold the mesh
- low-poly circle in Tinkercad may actually be beneficial for this purpose - bit more room for error?
- designed to be about right (ID = tube OD + 1 mm), but final fitting had to be tried with small adjustments in Slic3r (P4/P5: 100.4 % scale)
- 20 % infill, 0.3 mm layers
I also made a "mesh wall" prototype but quickly discarded this approach because it required silicone caulk for assembly. Therefore, it was messy to assemble and basically non-recoverable (i.e. properly cleanable/repairable) without any noticeable benefits.
