Bambu Lab XP Large Rear Poop and Waste Bin

Note: The current bin is shorter than necessary for the P2S. I am trying to figure how much taller it needs to be.

There are many poop chute/bin designs but this poop bin was designed specifically to address the following

1. Large enough to function as a plastic poop collector and as a plastic waste bin.
   1. Most poop collectors are well-designed but are just not large enough. 
2. Utilising the rear area of the printer only.
   1. Allow for the placement of objects on the sides of printer. In my case, a filament dryer.

Bin Capacity 

1. This bin is about 3.1 L and can contain about ~1158 poops. 
2. Calculations: Bin: 3081 cm3, Poop: 2.26 cm3, 85% Capacity: ~1158 poops. 
   1. Capacity of 3.1 L calculated at 15cm height as that is the height where the bin reaches the chute. 
   2. 85% capacity to account for spacing between poops. 

Printer Compatibility 

• Designed for P1S and assumed to work with X1, X1C and X1E with/without vibration feet. 
  • The original design works without Bambu's vibration feet. 
  • There is remix in the Print Profile for Bambu's original vibration feet. 
• Should work with the P1P with minor differences 
  • P1P does not have the side case, so there is a small gap around the edge. 
  • Unsure of P1P's default back cover material. If it is ferromagnetic, the magnets should work. 

Design Features

1. Maximum Height and Width utilisation of XP Series rear.
   1. Avoid blocking fans and allowing for filament holder.
2. Easy alignment and attachment of bin to printer.
   1. Poop Chute Insert, Rounded Edge Alignment and Magnet Inserts.
3. Level Indicator on Right Side of Bin only. 
   1. Allow of emptying of bin via the left side. 
   2. Available from 50% and higher to contain small plastic parts. It is a bin after all.
4. Compatibility with Rear Filament Holder.

Magnets and Magnet Inserts

• Magnets are not necessary as the bin is large and rests on the surface. 
  • But the magnets helps the bin attach itself to the printer and prevents gap between the printer and the bin from occurring. 
  • Also, magnets provide a smoother and satisfying experience of attaching the bin to the printer. 
• Accompanied magnets for the Bambu Lab scrapper can be used.
• Inserts are designed for 40mm by 15mm by 1.8mm magnets to be cut from Magnetic Adhesive Tapes. 
  • Magnetic Adhesive Tapes are easily available from amazon or hardware stores and can be reused in a wide range of applications. 
  • In America, 0.78" Width by 0.07" Thick will do. 
• Inserts' size are 40mm by 16mm by 2mm.
  • 0.2mm depth allowance for adhesive thickness and print tolerance. Noted that Magnetic Tapes list magnet thickness without accounting for adhesive thickness. Magnetic Tapes using 3M Adhesives has about 0.1mm thickness. 
• When using other sizes of magnet, the depth/height of magnets are important. There should not be too much of a difference as the magnetic force will exert pressure on the adhesive to tear off.

Notes

• Wall thickness of 2mm is used for strength and stability.
• 1mm was tested but display structural integrity flaws. The object was breakable along the length.
