Tapered cap for no spill cup

thingiverse

I was browsing through my designs and came across this mug, it's an incredibly well-designed item. I read the reviews and someone mentioned that a conical opening to the mug would help keep drips from running down its sides. I modified the design by making the lid taller and adding grips for easier removal. As of now, I haven't printed it yet. I'll update when I do.
