12 oz Sprite Bottle Funnel Insert

This is a simple scaled-down remix of my original, friction-fit, insert for a 2 liter bottle turning part of the empty bottle into a funnel with a screw lid.

I just scaled the original down to 60.3% which tightly fits the straight cylindrical part of the 12 oz. Sprite Zero plastic bottles. If the tolerances on your printer are too tight or too loose, scale up or down by 0.15% increments.
