Funnel for 2 liter great for Filastruder / Filabot

1/7/2016
I added the STL files of the funnel with male threads for those who would like to use it straight on to their filastruder, as well as an optional coupler so you can use that same funnel put the coupler on it and use it like my modified one without printing out 2.

I took the funnel which I really liked, but wasn't going to work for my application, however I like the original idea of the funnel adapter that emancipator designed!
I removed the inner wall, made it easier to print, and less plastic/print time.
Added the coupler from the other source PET Soda Bottle Coupler and made a threaded funnel!

So this way you can use the 2 liter bottles, fill them up with 2lbs and colorant, and cap them. Makes it much easier to fill the 2 liter bottles, and then you can tumble and shake to mix. You can then store them and if you like put desiccant bags in the 2 liter bottles until ready to use (working on an o-ring cap with a hook to attach a string to hold the desiccant or a cap that has a skinny cylinder to fit down the neck of the 2 liter that holds the desiccant either loosely or in packets.
