API Master Test Kit Holder and Drying

This is a test tube holder/drying rack for the API Master Test Kit. It is meant to fit over the box where you store the chemicals.
I remixed this design to fix a couple things.
The posts for drying the tubes broke so i made them print as separate part so they can be replaced, also since printed horizontally instead of vertically they should be much stronger.
I also moved the cap holders to the back so they'd be easier to grab.

I can't link this to the original right now but it's a remix of this design: https://www.thingiverse.com/thing:3968946
