Upgraded Poop Bucket for P1P/P1S. 
Transparent window allows easy checking of the bucket, holds on 4 magnets 8x3 mm and can be easily put in place with a small alignment part.
Available variants are 50 and 100 mm depths with and without supports. 
Bucket has a cutout not to block the printer vent. 
The variant with supports looks cleaner to me, but I uploaded all the variants for you to choose!
The variant without supports has 20° overhang, so I recommend slowing down the print for this part! (I of course forgot about it and my printer managed).
If you want the transparent window, you will need a 19x175 mm sheet of clear plastic (I used 0,2 mm thickness) and just slide it in. If 0,2 mm thick sheet is used, there is a “lock” at the bottom of the groove, holding it securely in place.
If you want the window covered with just a transparent filament, this option is also included in the 3mf file.
