LG Vacuum Cleaner Nozzle Brush Insert (Replacement for 5249FI2438A)

Summary:
This is a 3D-printable replacement for the discontinued brush attachment part of the LG wet cleaning nozzle (Part No. 5249FI2438A). Since the original part is almost impossible to find in stores, this model allows you to restore your vacuum's wet-cleaning functionality for upholstery and carpets.

The Design:
The model is designed as a multi-material assembly to mimic the original's functionality:

• Main Frame (PETG): Provides rigidity and clips securely onto the transparent plastic nozzle.

• Brush/Squeegee Part (TPU): Flexible edge for effective water extraction and surface agitation without scratching.

Compatibility:
Fits LG washing vacuum cleaners using the small upholstery extraction tool, including models in the V-C91..., V-C93..., and V-C95... series (e.g., LG Hippo, LG Turbo Extra).

Print Settings & Recommendations:

• Material 1 (Frame): PETG (for chemical resistance to cleaning detergents and heat).

• Material 2 (Soft Edge): TPU (Flex).

• Infill: 15-20% for the frame, 100% for the TPU lip.

• Supports: Minimal supports might be needed depending on your printer's bridging capability for the clip mechanism.

• Assembly: Designed to be a snap-fit or friction-fit, depending on your tolerances. (If you made it as two separate parts, mention if glue is required).

Why PETG and TPU?
Using PETG ensures the clips won't snap as easily as PLA and can withstand the warm water used during cleaning. The TPU part is essential for creating a seal against the fabric to ensure strong suction.
