Screw on poop chute designed for P1P and P1S (unsure but probably works with X1). Uses a small bin at the end of the chute that can sit on a desk to collect excess filament. I created it as I didn't want to attach a chute using magnets but also didn't want it to be too hard to remove the excess filament when it had built up. Does not work with rear spool holder.
I used 2 M3x12mm screws to attach it where the chute normally attaches to the back of the printer.
