Tom's M1 Spray Bottle Funnel

thingiverse

As seen in Monday Night Meatloaf 147! https://youtube.com/watch?v=jTiqPJGvFlA This is an application of, really almost a remix of, Necks and Caps (closures) by xavan. https://www.thingiverse.com/thing:1654620 I have gallon bottles of various concentrates or oils that need dispensing from time to time into smaller containers and spray bottles. I saw a commercial one for sale at one point and was shocked to see what they were charging and the funnel mouth was not much bigger than the bottle opening. This funnel threads onto the usual garden variety bottles and is vented to make filling easier. If you need a different bottle opening, you can modify the OpenSCAD file and spec out different bottle mouths. I shared it with my friend Tom when I sent him some expensive hydrocarbon happiness. He seemed to like it. The attached vent tube gets grafted into the scad file- i could not figure out how to loft and extrude the vent tubein OpenSCAD. You might have to poke through the funnel sidwall to open it up where the funnel crosses the vent. Your mileage may vary. Consider chemical compatibility when choosing filaments- ABS is soluble in Acetone, etc... .
