K8400 trash Can by Ekdahl, beveled edges - no support - mod

Great idea by Ekdahl!
- I felt a need to bevel the edges, so that debris won't accumulate there.
- Chamfered the bottom of it, so that it will be easier to clean out and insert.
- I modified the hooks, to be stronger and better looking.
- The hook modification was also to allow for printing sideways. This makes the hooks even stronger, eliminates the need for printing support, and best of all; the print lines are now in the trash bin insertion direction, which makes it slide in very nicely.
