Test Tube Rack - Aquarium Tester
thingiverse
This Test tube rack is designed for small 14mm Aquarium test tube kits. It holds 3 test tubes as I only regularly test Nitrates, Ammonia and PH. The top is a simple press fit into the base, it can be glued if you wish. The step file has been added so you can change the design as you see fit. It's very basic but does what I need. Any questions or if you would like something changed or completely designed please comment.
