About this 3D model

The API Freshwater Master Test Kit is the gold standard for checking the water chemistry of your aquarium. But it comes in a really poor quality container that is impossible to use regularly. Using this design and a syringe, I am able to keep test time to under 2 minutes. There are a few different designs: Master Kit: stores 8 test liquid bottles and 4 test tubes with the typical labels Hardness Kit: for measuring hardness. Two different pH kit designs: one deep and one wide. I've also included my OpenSCAD file so you can customize as necessary.
