every last drop - bottle consolidation funnel

thingiverse

Originally posted on July 15, 2013, the updated .stl files for the funnel ensure watertight meshes for both "top" and "bottom" parts. Apologies to those who had difficulties printing these parts earlier. The inventor aims to use all shampoo and detergent in bottles but finds holding them upside down inconvenient, especially for the last drops. This inspired a funnel design that securely holds two bottles together, allowing the last contents to transfer at their own pace. Compatible with bottles under 100mm diameter, this funnel set consists of a top funnel and a bottom cylinder. The maker claims it's a two-part print, but hasn't tested it yet as the Makerbot is due in two days. The walls are designed to be 2.5mm thick.
