thermoflask 25oz Soft Touch ring

25oz Soft Touch Traveler Bottle replacement ring handle and keyhole and slot for adding cotter pin. Original pin might not grip PLA PETG much, so I hacked up a cotter pin. The pins cost me about $2.50 Canadian, but there might be other ways. The original pin diameter is ~2mm so I had to snip off part of the cotter pin and strategically bend the ends hence the recessed areas on the arms.
