API Freshwater Master Test Kit+ Caddy

The API freshwater master test kit comes with 7 bottles and 4 test tubes, all packed in a tight case. The case isn't really functional, and when I added 2 more bottles for a water hardness kit, it was awkward to store.

I designed this caddy to store all 9 bottles with room for one spare. I included standing storage for 6 test tubes and a pipet to help with filling them accurately. I also created a slot for holding the instruction manual. The placement of the manual serves as a backdrop for reviewing the values of each test. Printed on white PLA so that the color doesn't impact the test results.

These are the items used in my kit as pictured (No sponsorship):
