I've designed these after using the zojirushi thermal flask for a number of years. These are to protect the flask.

I tried to locate an existing design for these thermal mug/flask protective boot and sleeve but to my surprised, I couldn't find any that fit. So, I spent half and hour or so and knocked up these designs. 

As you can see from the used Zojirushi thermal flask, the wear pattern tend to be at the bottom (obviously!) and mid way. So the designs were based on that. The sleeve offers better grip than the bare aluminium.

The boot will fit both the zojirushi and thermos travel flask/mug. The diameter for this is 65mm. 

I made the protective sleeve 0.5mm narrower (64.5mm) to give them a better hug to prevent it from sliding down. It is a very tight fit so you will have to force it down a bit. However, this made the sleeve incompatible with the Zojirushi flask. But you should be able to scale it down accordingly in the slicer. The wall thickness is 2mm.

I printed these using sainsmart tpu on my prusa mini using 0.6mm nozzle. I was able to print these using vase mode.

Hope these will be useful :)
