Hanna Checker Cuvette Drying Rack

I've been drying my cuvettes upside down on a paper towel after washing and it's pretty easy to knock them over. Drying them face down minimizes contamination and dust particles from settling in, and possibly messing with the results. I designed this to hold 12 cuvettes along with their caps. Caps are meant to be placed down and has a channel for the water to drain.

I have a 0.25mm tolerance on parts, so scale accordingly. Should print fine with no supports.
