Nutrafin GH KH Test Kit Holder

thingiverse

I needed a holder for my Nutrafin aquarium test chemicals and test tubes. Compared to the API test kit, the Nutrafin bottles are rounder and the test tubes are larger in diameter. To print it standing up, I oriented the design as I would use the holder when it's done. This ensures that the GH and KH labels are upright, not on their side. The 3mm deep inset was a challenge to print without stringing. To prevent this issue, I added supports, which were necessary for my first design. Next time, I'll make sure the inset isn't so deep, but for now, I'm learning as I go with this software. The test tube and bottle cavities have small holes at the bottom for drainage. This feature is useful for those who prefer to keep their test tubes upside down for drying when not in use. I've designed this holder to be stable and secure. Adding water or chemicals doesn't cause any tipping or wobbling, giving me complete confidence in its performance.
