Milk carton breather

thingiverse

I made it for myself to keep the milk from splashing out of the carton. I left the top intact to make it easier to pierce the carton. The idea is that air can enter your carton, preventing it from drawing vacuum and thus splashing. Instructions Print with base down, STL is good to go. I found it easier to print in PLA because pointed things always bend when I use ABS.
