Bottle

support, everywere, it has a tethered cap witch slots into the bottle in four different parts, prints perfect in tpu, ment to be printed in tpu, if you print the bottle in another rigid material, make sure you print the cap in TPU 95a is the best, i recoment both the cap and the bottle in TPU 95A because you get a perfect seal with no water or air leaking with makes it even less prone to take in water because it floats, use infill at 15%.
this idea originated from the need to open my cats snack bag without them hearing anything iopen up and be acting weird over snacks XDDDD...now i put a nice ammount of snackies in the bottle, and keep that around my desk so i can surprice babies with some snacks when they are full sleep XDDDDD, then it merged into a hole thing of small vials for pills and then a grip for the short bottles and then a ring, then a key loop on it, works out so well, i love them....enjoy humans.
it is printed with tpu, even the tpu is used as support with proper settings
