I kept leaving the thermos behind. I made the Dongle to be able to attach a carabiner or something to carry it with. I used a teal TPU to match the Yeti color. I also made one in Red/black. It has held up for months thru the summer and winter. I can hang it from a bag and keep my hands empty. Tab is bulked up to withstand the stress at the top. Inset to push it out a bit from the lid.
Slow the speed in the slicer to 25mm/sec.
Temp for my TPU likes 210 nozzle. and 55 for the bed
No supports.
I sliced it in Cura.
