Following my previous model P2S Buffer Guide + Quick Release , here is a variant for the new Bambu Lab X2D.

The goals are still the same :

• keep the perfect alignment of the PTFE tubes, and keep this as close as possible of the internal sliding system, where other models are sometimes bolted far away from the Buffer, this one will guide the filament at the entrance and at the exit of the system. This can remove issues with retractation error messages when the AMS failed to pull or push the filament, it also reduce the wear of the mechanism and the PTFE tube as the filament has less friction

• add a quick and tool-less release of the PTFE tube is an obvious advantage : with a small push on the buttons the PTFE tubes will be released, no need for a tool anymore, no need to fight with the tip of your fingers anymore. It is even better if like me the access to the back of your printer is not easy

(P2S Buffer Guide is shown below, X2D Buffer Guide functions are identical)

• …and refine the look to make it as most “OEM” as possible. I hope you will like it, even if it is a not very visible area of the printer!

  This time there is no need to deal with the buffer internal components, you just have to bolt your X2D Buffer through the Base Bracket, which holds the release buttons. So the look will be even cleaner than before :

❓ You will need a total of 54g of the filament of your choice : PLA is sufficient here, it is stiffer and this area should not suffer from high temperature or UV, but PETG will also work (probably fine as well with PETG-CF, ABS, ASA etc…)

The model is composed of 5 printed parts :

• 1× Base Bracket with opening for the Buffer connector, which holds the buttons
• 2× Input Buttons. They rotates around a piece of filament for a smooth and reliable movement
• 1× Output Button, it also rotates around a piece of filament
• 1× Rear Shim that fill the gap of the rear panel dimple, and allows to move the assembly to the left (in order to increase the gap around the poop chute)
• optional : you can use TPU inserts to damper the noise of the buttons (totally over engineered I agree but still a nice addition)
• You will also need 2 short pieces of filament for the buttons assembly (PETG if possible)

🧰 Extra Supply : For this model, you will also need the following parts

• 2× M3-30 screws (which replaces the original Buffer screws)
• 1× M3-8 or M3-10 or M3-12 screw (length is not important here)

🔧 Assembly : Take a look at the enclosed Assembly Guide at the bottom of this page. It does not request any special process, you just have to insert two pieces of filament into holes, to create the buttons articulations

🔨 Disassembly : there are access holes on the bottom of the buttons to push out the filament pieces should you need to explode the assembly

I hope you will enjoy it. As always : do not hesitate to reach me by message should you find an improvement or need of an adaptation.
