There are a few time the poop chute get clogged up with extended poop like a hook. Most of the time, the poop will hang over the top of the blade flap. It will start to accumulate more poops for multi-colour prints and that may lead to fail prints.
There are few poop chute cover out there, but none of them stop the poop from clinging over the blade flap.
Feel free to remix this model (STEP file in RAW download), hot filament will not be an issue usually because the tool head will cool down the filament before cutting it loose, but I still recommended to print with PETG, ABS, ASA materials.
I only tested it on my P1S, I do not have X1C or P1P if they fit as well.
Additional mod appears in the photo due to popular question; it's the A1 wiper mod for P1 X1.
