Bottle Joiner

We use large pump bottles of Shampoo, Conditioner and body wash. The pumps don't get all the product out so, I designed this to allow the rest of the product to be poured into the new bottles. I wait and use some of the new to make sure there is room for the remaining to fit in then just put the new and old bottles together and let gravity do the work over night. The tube goes into the used bottle to allow the air to transfer easier. I used tree supports in Cura and they were easy to remove.
