Bambu Lab Magnetic Poop Chute to Segmented Tube

It's a simple magnetic interface that directs the Bambu poop through the segment tubing.

Update 2/12/24: After about a week from uploading the original model, someone mentioned that the tube connector was backwards and was catching the poop (I didn't experience this because I don't bend my tube much, but I saw how this is really possible), so I reversed it and uploaded new photos and model files with the opposite tube connection.  I also beefed up the tube connection a bit and removed a little from the bracket to try to keep it light weight.  

The Printing

What I used to print this and some settings I found helpful

• Bambu X1C
• PETG
• 0.6mm nozzle
• line width: 0.8mm
• 2 walls
• tree supports on the hanging edge
• wall generation: Arachne
• 15% Cubic infill

I highly recommend using ‘Arachne’ wall generation as it allows for better wall printing for the hood (the opening to the segment) and better magnet holes and the poop opening.

If you're using a 0.4mm nozzle, I would suggest you use 3 walls in order to help with printing the panel at the angle.

About “Classic” vs “Arachne”:

The classic wall generator produces walls with constant extrusion width and for very thin areas, gap-fill is used. The Arachne engine produces walls with variable extrusion width.

Print orientation

This prints segment tube to the plate.  I have pretty good bed adhesion on my textured PEI plate, so I didn't need/use a brim.  Feel free to add one if you think you need it.

I manually controlled the supports to only apply to this area…

The Magnets

I used four 12x3mm magnets (I used some from this combo pack I've had for a bit https://www.amazon.com/gp/product/B08HQMT9BD)

The four magnets hold well against the X1C and all 13 tube segments that I have attached and pointed to a trash can under my desk.

PS notes

Side Note: The photos show a plate that has some thinner sections on the sides, but I found it was unnecessary and actually negatively affected the print… so I simplified it after the print was complete.

PS. This was inspired by the craycray design from MakerWorld.  I wanted bigger magnets, a simpler transition to the tube segment and more of the model to be support-free.

I like the idea of the segment tubes, and the magnetic mount that CrayCray created was close to what I wanted.  I wanted a simpler design and something to support bigger magnets.

This design has a straight shaft from the bracket… and has 12mm x 3mm magnet holes.
