Don't get me wrong, I love my Bambu P1S with the AMS. But one thing I DON'T love is the way it chucks the blobs of extruded filament out the back of the printer when it's multicolour printing. If it were on a bench next to a wall, that would be fine, but mine is on my desk. I have to get into my work area by passing behind the printer, so I kept wondering when I kept treading on the hard little blobs of filament which it was being thrown all over the place. So, since the printer works so wonderfully fast, I could print this large splodge catcher, which fits against the back of the printer and catches all the rogue splodges. I was so happy with it, I wanted to share it with you all too! Enjoy :)
