A1 Sewer Line - Poop Chute

Introducing the Bambu A1 Sewer Line! Your front-disposal solution.

I got tired of either needing to empty out a poop container or cleaning up stray poop flingers. Since my A1s are placed on the front of a long table, I figured the best way to take care of the poop would be to route it off the front and into a wastebasket. This system drops the poop onto a ramp which carries the poop forward and off the front edge of the table. The ramp even has a hinge mechanism, to allow for the dropping of the z-axis. So far, the system has worked flawlessly for me; The Z-axis is either high enough to gravity-accelerate the poop directly to its destination, or the motions from the machine gently vibrate it down the track.

Update (11/24) : After using this for a little while now I've found that raising my printer (on top of a storage system, for a nice storage solution) made this work significantly better. I also think that a software solution of raising the z-axis to something like 100 after every filament change could get around this, but I haven't tested it.

Assembly Instructions

Assembly is relatively simple and requires just 2 M3x10 screws with socket heads (or something similar - M3x8s also work).

1. Start by snapping the ramp together
2. Insert the ramp into the holder.
3. Screw two M3x10 screws into the holes to capture the ramp.
4. Set the mechanism on its side and gently tap the associated side shroud on with a mallet or similar tool.
5. Flip it to the other side and gently tap the other side's shroud on.
6. Now that the assembly is complete, simply press-fit the entire device onto your A1's filament ejection mechanism.

Note: It's definitely possible to create a hardware-less version of this, where you print your own press-fit hinge hardware. I just personally prefer the rigidity and reliability of the M3 screws, and I have a ton of them (If you're designing for 3D printing it's good to have a box of them, because they have infinite uses). If someone wants to take that on, have at it, but I probably won't.

Printing

I printed these in PLA (Specifically Prusament Galaxy Black), but I'm sure any rigid filament type would do. It takes around 1 hour in ludicrous mode.
