This design appears to be 220VAC only. And I’m assuming all metric threads and other measurements, too.

I think I could live with all the other components being metric, if they just had a way to work with standard U.S./Imperial containers as well.

Oh, and they need a 120VAC design for the motor and all the electronics inside.

Or, a design that can handle both 120VAC and 240VAC, as well as both 50hz and 60hz.

It's open source, you should make these updates!
