Legs
thingiverse
Created custom legs to take advantage of these 6x2mm grips I had laying around: https://www.amazon.com/gp/product/B01N90V0MB Otherwise I'm sure you can get away with printing a 6mm disk out of TPU. The bottle has a lip so the adhesive doesn't slide around. Print upside down with supports.
