Milk Frother

This object makes fine, consistent foam for espresso drinks. I chucked it in a drill and, in under a minute, the milk had doubled in volume.

To complete this build, you will need two light springs. The ones I used where 40mm long uncompressed, 6mm in diameter, and had a wire OD of 0.5mm. Once printed, thread the spring onto the part as shown in the pictures.

Use food safe filament such as PETG and make sure that the print is as smooth as possible. Milk left in small cracks in the part would be a great way to grow bacteria so please, please make sure your prints are smooth and use a food safe coating if possible.

I found that it works best to use 2% milk at 150 F (65 C).
