API Vial Holder (3-pack)

Many people in the Aquarium hobby use the same API water test kits to test the water parameters. They all include the same size glass vials that tend to be super fragile.

I made this print to hold them nice and firmly, similar to normal vial racks.

Comes in two pieces for ease of printing and simply slide together. I found the stuck well enough but you can glue them if you don't want them coming apart.
