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.

The chute I modified from something I found so it fit my feeder better. You may be able to find one for the WoPet on Printables. I think I remember seeing some that were made specifically for that.
