Scrap Bin for Replicator 2

I got tired of picking filament scraps out of the bottom of my Makerbot Replicator 2 so I designed a bin that is sized to fit up against the opening on the front of my print where I could sweep all the crap out of the printer base (I use a small 2" wide paintbrush for a broom) into a bin and I empty once it starts to fill up. Raft pieces, support material, filament scraps from changing spools, etc...
