API Test Tube Stand

cults3d

This is a handy test tube holder designed specifically for aquarium water testing. When printed in white, it provides an accurate reading of your water quality, making it easier to get precise results compared to simply placing the tubes against a small booklet. The design includes clever features like drain holes and TPU feet that prevent the stand from sliding around on your countertop even when wet. You can also use regular gumdrop feet if you prefer not to print the 3D feet.
