I created this exhaust hose adapter for Bambu Lab P1S to reduce bad smells while printing with ASA and ABS filaments in small rooms.

The adapter has slots to add a hermetic seal and improve the overall performance.

The assembly is easy, use the 4x M3 holes beside the exhaust output grid in the rear panel. You must remove the existing screw on the left, and use 3 additional screws (top, bottom, right) to fix it.

I recommend using a PVC flexible exhaust tube for 3" (8 cm) tubes fixed with a metal clamp.

My original 3D model is publicly available on OnShape. You can modify it to adapt to your requirements.

I also provided a version with a 90° angle.

Settings:

• Filament: PETG
• Layer height: 0.2 mm or adaptive layer to obtain a smoother surface
• Infill: Gyroid 15%
• Supports: Normal supports only on the build plate
