Bottle Draining Funnel

thingiverse

This handy gadget makes it easy to pour the last drops of one bottle into a new one without the hassle of juggling two bottles that might tip over. It's perfect for showing off your 3D printer skills - just look at this! The device is designed for standard 27mm OD and 20mm ID tops commonly used on shampoo, hand wash, cleaning products, and similar items. No threads are needed; it simply clicks into place with a push fit. I whipped this up quickly for my housemate, but keep in mind that it's tailored to my slightly over-extruding printer, so the fit might be looser on another one. If anyone knows what those threads are usually called or sized, feel free to leave a comment and I'll update the description!
