Aquarium water test kit holder / rack

thingiverse

This is a customized holder for all of my aquarium water testing supplies. It includes spots for: 1. Each item in the API water test kit (including the manual/color chart) 2. A bottle of 100ct Tetra test strips 3. A pipette for transferring the aquarium water to the vials There are also slots for building a bridge to use 15ml plastic test tubes rather than the glass API 5ml tubes. The optional supports give the tubes a little more stability. If you want to use the supports, print 2x of the legs and 1x of the bridge. Also, don't feel the need to comment and say my Nitrites and Nitrates are high... I'm cycling my tank before adding fish :) *** UPDATE: Since the glass vials that come with the API kit are expensive and break easily, I've started using the plastic 15ml vials instead. I wanted to be able to flip them upside down to dry out between uses, but the bridge holes weren't big enough in v1 so I made a v2 of the bridge with wider holes.
