NT Labs Water test Kit Tray

This is a my 3D printed holder designed for the NT Labs water test kit. The original cardboard tray it comes with is pretty flimsy, so I made a sturdier version to keep everything organized and secure.

It holds all the reagent bottles, test tubes, and the small syringe nicely. There's also a slot at the back to fit the colour comparison cards – just cut them out from the original NT Labs box and slide them in.
