Bottle coupling/draining device

thingiverse

When working with viscous liquids from bottles, I dislike waiting for nearly empty containers to drain before use. To circumvent this inconvenience, I transfer the remnants from almost full bottles into new ones. Due to the time it takes for viscous substances to fully drain, I designed a coupler that enables me to connect two bottles together, allowing them to drain unattended while overnight. The internal structure of the coupler features a small funnel-like shape with a nozzle on one side, suitable for positioning at the bottom during draining. The diameter and thread size are commonly found in many bottles. While printing this design, I encountered issues with adhesion to the print bed, prompting me to modify it by adding an inner ring that increased contact area and resolved the problem. However, after printing, this additional feature needed to be removed. Both modified designs are included: one with the bed adhesion ring and another without. For optimal results, it is recommended to print the threads at relatively low layer heights, such as 0.1mm. No support material is required for this design.
