Understood, I just want to make mine safer. I didn't start making these to sell a bunch of them- but it is nice to sell a few, unemployment sucks. They made me a suppling Modder/ Manufacturer lol what a joke. I make these at my kitchen table- one at a time. I decided to try and keep making them better, because I wake up and use it everyday. This is only an extention of that.. Sometimes the way I describe thing I might tend to make them sound as good as possible maybe even better than they are, well I'm Irish. If I made what I think are improvement sound like the end all solution well it just isn't so. These vent holes are the best idea I could think of.
