Like poopipe says you can hack the blending of the handle by floating it over the bin. If you flare out the open edgeloop at the base of the handle you can trick the baker into baking what it perceives is a continuous surface normal. Like a floater.
That's just down to not setting the right projection distances. There's plenty of material online about how to work with floaters so it'll be easy to resolve. WRT things like text/screwheads/panel gaps - I recommend just bashing them into a height map in Painter, it's just not worth the trouble modelling them and then…
Projection distance is how far out along the normals of the low poly mesh the Baker searches for things to bake. If you use a cage it'll search up to where the cage is, if not it will usually use a set distance. Good settings to start with for substance bakes are 0.01 forward and 0.5 back (in Bounding box space) . If…
