P2S Nozzle Wipe Anti-Scatter Poop Shield

[⚠️ATTENTION: 2026-04-16] Important Note on Nozzle Wipe Path With the recent update to Bambu Studio, the nozzle wipe path has changed. Previously, the wipe sequence started from left to right, but in the new version, it begins from right to left.

I am currently investigating the most effective cutting method for this new movement. As a temporary solution, the easiest fix is to cut the tape along the path where the nozzle moves from right to left to avoid any interference.

Why I Created This

I was constantly frustrated by "micro poops" (tiny filament fragments) scattering randomly across the build plate during nozzle wipes, which often ended up embedded inside my prints. I used to have to watch the printer and manually clear these bits before every print, so I developed this physical shield to eliminate that stress and keep the print area clean.

Overview

Specifically designed for the Bambu Lab P2S. This shield physically blocks micro poops from flying onto the build plate during the wipe sequence. As a secondary expected benefit, using insulating tape allows you to utilize static electricity to actively attract and hold these tiny fragments.

What you need

• Transparent Tape: Width of 4cm or more is recommended.
  • Kapton Tape (Recommended): Excellent heat resistance and insulation properties. 
  • Packing/OPP Tape: Can be used as a substitute. It has been confirmed not to melt catastrophically at standard PLA printing temperatures.
• Printed Parts: Shield Main Base, Folding Assembly Jig, Shield Stopper Rib.

Step-by-Step Guide

The goal of this guide is to create a high-precision transparent shield by encapsulating a 3D-printed "Rib" inside adhesive tape. Attempting to do this without the jig will result in a messy, misaligned shield. This internal rib is essential because it acts as a mechanical lock, ensuring the shield remains securely fixed in the base and never falls out during operation.

1. Setup (Photo 1-3)

Apply a piece of tape (4cm+ wide) to the smooth surface of the Folding Assembly Jig. Then, flip the jig over to expose the adhesive side and attach the Shield Stopper Rib (9cm long / 0.2mm thick) onto the designated position.

2. Fold and Press (Photo 4-5)

Close the jig and press firmly, pushing any air out from the center to the edges. This securely encapsulates the rib within the tape.

3. Cut to Shape (Photo 6-7)

Use a craft knife to cut along the slits in the jig and trim away the excess tape. Once cut, you can smoothly pull the finished Transparency Shield out of the jig.

4. Assembly (Photo 8-9)

Slide the finished shield into the grooves of the Shield Main Base. The internal rib acts as a "stopper," ensuring the shield remains securely fixed and won't slip out.

5. Installation and Final Adjustment (Photo 10)

Slide the entire unit onto the P2S near the purge chute. 

Important Calibration Step: The home position can vary slightly between individual machines, so this final customized step is crucial.

• Marking the spot: Run a test print with PLA. The toolhead will lightly collide with the shield, leaving a perfect "marking" on the tape where the nozzle tip is.
• Cutting the notch: Remove the base and, using a pair of scissors, cut a notch approximately at the marked spot.
• The Benefit: This notch ensures that even if the nozzle tip has debris attached, it won't rub against the shield's edge as it passes. This prevents debris from being deposited along the toolhead's path and significantly reduces the chance of scattering waste across your printer.

Notes & Disclaimer

• Disclaimer: The designer is not responsible for any damage or trouble caused to the printer through the use, installation, or misuse of this model. Use at your own risk.
• Materials: PETG, ABS, or ASA is recommended for long-term heat resistance, though PLA is confirmed to work for the base and jig at standard temperatures.
• Maintenance: If the tape becomes dirty or loses its "stickiness" for debris, simply replace the tape using the jig.
• Clearance Check: After installation, always move the toolhead manually to ensure it moves smoothly to the home position without interference.
