I don’t like the bulky cases that came with my test kits and found a case at harbor freight I can customize and keep my test kits all together. That is still a work in progress. However I printed a little insert for my case to hold Hanna cuvettes. I had planned on making a drying rack insert for the front compartment but may not. Here is the STL if interested (https://www.thingiverse.com/thing:3892534/files)
The cuvettes are raised up so there isn’t a gap between the covers of the carrying case top allowing them to fall out when transporting.
