Thanks for the guide, but I was looking for something to help with the blend stick part. I was running it and the bottom part (blade, steel cup above the blade, plastic "gasket", plus shaft) just popped off. I can whap it all back together but I don't trust it to stay together. Looking for advice to repair in a permanent food-safe manner.

Another vote for reassembly. There are a lot of adhesive bits with a blue backing which I'm pretty sure are for attaching the screen, but one appears to be a pull tab for the battery (but only 1 not 2). There's also a long strip with a red backing. I have no idea where that one would go. Finally, one of the screen adhesives stuck to the inside of the box so it's unusable now.
