64oz Vacuum Flask Growler Handle

I made another handle some time back which was...okay. This one's better. It's slimmer, lets you grip it closer to the mouth of the bottle, and it uses a lot less plastic.

It does require a couple of hose clamps, but they work really well. The ones I purchased were marked with a diameter, and were ⌀64/114mm for the top and ⌀127/178mm for the bottom.
