My wife does quite a few different crafts and always collects debris on her workbench, this little "scrap catcher" sits on top of a drawer and allows her to sweep everthing into the bin. It's easily removed and dumped into the garbage.
Supports are needed for the handle that hooks over the drawer itself. I was going to design it a bit differently so it didn't need supports (2 or 3 part system), but this is the way she wanted it. The supports print very easily and don't really take too much filament or added time.
