Transfer Funnels

Update

This model has been superseded by Transfer Funnel & Adapter System .

---------

It is always slow to drain the last bit of thick liquid stuff from its container. This presents a small challenge when trying to save it. I found my wife using funnels and clamps and trying to balance them for a transfer to the new container.

Design

So, I designed this solution in Fusion 360 (included).

It is two funnels that screw onto the containers and magnets to hold them in place for the transfer. I added a window on the upper one so you can monitor the progress.

I set it for 8x3 magnets, but it will work with a range of 6x1 to 12x3.

The thread size works for many bottles. I have tested it on several brands (see pictures). I have included a quick printing “thread screw test” you can use to confirm it will work on your bottles. If you are experienced in Fusion 360 and careful, you could change the threads (adjusting the coil settings).

It is an easy print with no support. I used Prusa Transparent to help see the progress of the transfer.

Usage

I would recommend these steps:

- Ensure the destination bottle has enough room to hold the source contents. - Screw the bottom funnel (the one with no cutout) onto the destination bottle. - Screw the top funnel onto the source bottle. - Carefully and slowly start tilting the source bottle – with the cutout side up – over the destination bottle. - When you are sure you have the bottles positioned so the contents will remain in the funnels, rotate them for magnet alignment. - When both are aligned and the first magnet is set for contact, finish tilting the source bottle until all 3 magnets snap. - Watch the start of the transfer to make sure it will not overflow before leaving it unattended. Note: This is meant for slow, thick fluids that take a while to transfer. For thin, fast flowing fluids, I would recommend a regular funnel and not leaving it unattended. See my “ Funnel with Fins ” model as a possible solution.

Note: If this model is not the correct thread size for you bottles, you may want to consider my “ Bottle-to-Bottle Funnel ”.

Note: This solution will solve the actual transfer, but you may still have a tall unstable conglomeration that needs to be propped up to prevent it from falling over. See my “ Adjustable Holder ” model for a solution to that problem.
