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 wasn’t a huge hassle to fill their feeders, but of course, that’s what 3d printing is all about. Not necessarily fixing a problem, but making things more efficient and convenient. And it’s super nice to just have my dog food (which is on a subscription to be delivered monthly) show up and just fill the container and I don’t have to worry about them being fed because my schedule can be all over the place at time. I even have an automatic sliding door so I can let them out remotely if need be. At home, I just tell Alexa to open the door to let them out.
