Renpure Bottle Coupler

prusaprinters

My wife regularly uses Renpure products, but they have a major issue with the lotion products; the pump leaves about a week or two worth of lotion in the bottom of the bottle and she has a hard time getting it out.  I thought why not print a simple coupler that would allow her to drain the end of one bottle into a new one?I looked at existing couplers, but they did not fit correctly.  So, I created a simple one that you can friction fit over the top of the bottle to the rim without threads (see picture).  This allows product to flow from one bottle directly into the second.I created this bottle coupler in PrusaSlicer using the negative volume feature, so I cannot generate an STL file.  I printed this with Overture PETG at 0.20mm QUALITY settings but modified filament settings of Overture.  Open in the slicer and change as you require.
