Pondlab 200 holder

The original cardboard box for my Pondkit 200 broke so i made a holder for the included materials and also for a syringe i use to get the right amount of water in the test tubes. There is a notch in the back of the holder where you can put the original cardboard with the color-codes for the tests. When i printed this in generic PETG i had some slight warping. This is was the cheapest possible PETG at around 10$ a kg and i haven't cleaned the buildplate in months so i believe thats why. But look over the settings before you print to make it suite your filament.
