I was tired of standing around for 10 minutes while my body wash drained from one container to the other. Instead, I spent 30 minutes in FreeCAD, 45 minutes printing, 3 minutes standing it up, and 7 minutes sitting there smugly.

Designed for Dove Mens Body Wash pump-dispenser to receive from the large size non-pump. I included the FreeCAD file so you can change diameter if you need.
