64oz Vacuum Flask Growler Handle

thingiverse

I designed another handle some time back which was somewhat decent. This one's an improvement though - it's slimmer, allowing you to grip the bottle closer to its mouth, and uses significantly less plastic. It does necessitate a couple of hose clamps, but they function exceptionally well. The ones I bought were marked with a diameter, and were 64/114mm for the top and 127/178mm for the bottom.
