Aquarium test kit - test tube rack

thingiverse

A device for holding my aquarium test tubes that would serve as both a display unit and a storage facility when conducting water quality tests, while also functioning as a drainage/drying system. Small feet and holes at the bottom of each tube holder enable efficient drainage/drying. A line indicating 5ml is printed on each slot to facilitate accurate testing with API test tubes or similar, which typically requires a volume of this size. If printed in white, the semi-circular slots provide an even background color, making it easier to compare test results against color charts. Print Settings Printer: Cocoon Rafts: No Supports: Yes Resolution: 0.2 Infill: 20% Notes: Some users may encounter difficulties slicing this design correctly using Cura due to issues with the base holes not functioning properly. One possible solution is to flip the device on its back, which will require supports for the base holes.
