Time for the next installment in our "Made in the USA" series, telling the story of making here at Rest Devices.

As we've shown before, we use our CNC Mill and 3D printers to rapidly test new designs and functionality. We also love to stay as close as we can to every aspect of our product development, so we build everything ourselves.

Today, we're prototyping new ways to heat and cool a bottle for the next Mimo product coming off the line: the Smart Bottle Warmer. The part being 3D printed here is a prototype of what a bottle would sit on inside our bottle warmer. Testing individual parts like this often gives us new insights into how complex components will interact with each other.

And no, I didn't plan on dressing to match the parts.
