Test Tube Drying Rack for Aquariums

A drying rack for test tubes with a tray for the caps. Each pole measures 98mm. I made this specifically to dry the test tubes I use to check my aquarium's water parameters after cleaning them.

Simply place the tubes upside down on the pole and place the caps in tray so you don't lose them. 

I made this with these tubes in mind: 10ml Lab Plastic Frozen Test Tubes

I added 3 new models that include tube holders for the ones linked above as well as API test tubes if you use those instead with this model. Note: I haven't printed those out to test because I no longer use this print but I gave it some generous tolerances. Try out the separate prints first to make sure it fits and let me know if it doesn't.
