Hi, I'm glad you found one of my first boosters.

The dimensions are accurate to the waste from the flow calibration. 120mm(length) x 20mm(height) x 30mm(width)

I've already printed the poop bin of the filament my A1 produces. But I didn't want to mix the thin filament lines that are printed as flow calibration. I created a small box in which I put them separately.

You can also add it to a great trash can using my holder.
