NOTE: If you're downloading the STL files, the funnel is included but does not have the “.stl” extension. If you manually add the file extension, it will work. I've reached out to Tech Support to address this issue but in the meantime you'll have to add the .STL extension yourself.
This contraption is used to transfer the last few bits from the old, almost empty, bottle to the new one. You know, like for soaps, lotions, etc. It was inspired by the Smart Funnel (https://www.amazon.com/dp/B014JPCO5U/) which, apparently, is no longer available.
This version can grab a bottle opening up to ~38mm (~1.5 inches). It can hold 2 bottles (for a long period to get those last drops) or the funnel can clip onto a bottle to hold it steady while you pour into it.
The idea was to create something easily printable (no supports required) with no extra parts or components, like springs or anything. To assemble it, just slide the two long posts into the funnel slot. The two small tabs on the clamps are to keep the top clip aligned within the funnel (without them it can spin out).
There seems to be some deformation if the clips are held open for an extended period. I've printed it in PLA and PETG and both materials print fine. I don't know if one will resist “stretching out” more than the other after being held open.
