This Poop Deflector snaps into place inside the purge chute cutout in the back panel of the Bambu Lab X1 Carbon 3D Printer. It may also fit the P1 series printers if they have a common back panel. It eliminates the occasional overshoot of purge filament over the top of my purge bucket. The deflector has 3 tabs that keep it centered in the purge chute cutout and it has 5 recesses to install optional 10 mm diameter X 1.75 mm thick magnets if you want greater holding power to the back panel. The Slimline Purge Bucket by Brandon Raineri works well with this poop deflector. I trimmed his design slightly to allow me to slide it into place from the left side of the printer without coming into contact with my poop deflector.
