QQ-S Scrap Bin
thingiverse
My QQ-S sits on my desk and I wanted a scrap bin I could slide all the little filament bits straight in to from the build plate. This design is flush with the top of the printer without covering the air holes in the case and slides underneath by 10mm to keep it in place. If the back plate of your QQ-S looks like the one in the pic, it should fit. I can't guarantee the same for other QQ-S versions as they all seem a little different. As a bonus, you can easily slide it towards the back to cover the main power switch on these models to prevent accidental shutdown.
