Customisable Bottle drainer

thingiverse

This gadget connects two bottles together for draining old product into new or vice versa, allowing you to get the last of the product out.\r\n\r\nThere are many designs on Thingiverse, but after trying them, I decided to create my own:\r\n- No threaded connector was wanted. It can be fiddly to screw two large bottles together, especially when one is upside-down. Some bottles don't have threads, only snap-on caps.\r\n- A push-fit wasn't desired either. When the top bottle is full of liquid and slopping about, it's easy for the bottle to pull out of the adaptor.\r\n- A simple funnel was also not wanted. I wanted to leave this overnight.\r\n\r\n(I found a design I liked, but lost it. If I find it or you tell me, I'll credit the original author.)\r\n\r\nThis design is fully customisable: top and bottom pipe diameters can be changed, as well as the funnel angle. For more control, wall thickness and profile pointiness can be adjusted. The code should be easily understandable.\r\n\r\nWe now have a collection of these gadgets in different colours in our drawer: various sizes for connecting large to small containers, and an adaptor for draining liquid soap into a hand-made ceramic dispenser.
