My automatic dog feeders work great but only hold enough food for a few days so I designed and printed a funneling system and a resovoir to hold the entire bag so all I have to do is fill the resovoir when I get a new bag. Works great.
Edit: don’t know why the photo uploaded sideways. Sorry about that.

It’s super nice. You just twist the tank off and fill it from the bottom. And it holds a lot. I refill it around every 2 weeks. Had it for years.
