Slim Window Exhaust for H2D
Overview
This is a low-profile, vertical window exhaust system designed to vent laser fumes outdoors while staying tight to the wall and window frame.
It was developed specifically to support desktop laser setups (e.g. Bambu H2D 40W paired with an external fume extractor) where space efficiency, monitor placement, and aesthetics matter — without committing to permanent wall modifications.
The design routes airflow vertically along the wall and window, keeping desks usable and installations visually clean.
Key Features
- 100 mm outlet at the bottom of the assembly
- Slim vertical profile to preserve desk and monitor placement
- Window-mounted, semi-permanent solution (no wall penetration required)
- Modular assembly for easier printing and iteration
- Designed to pair with external fume extractors
Why This Design Exists
Most desktop laser exhaust solutions are either:
- Bulky and intrusive
- Temporary-looking
- Incompatible with real-world desk layouts
This design prioritizes form factor first, routing exhaust vertically to minimize visual and spatial impact while remaining practical for home and apartment workshops.
Print & Material Notes
- Designed and printed in PETG-CF
- Improved stiffness and temperature resistance compared to standard PETG
- PLA is not recommended for laser exhaust applications
- Components Adhered via 3d print pen sewing/welding (see image)
- Selective painted fuzzy skin was used to improve surface finish
- Note: enabling fuzzy skin increases slicing and print time
Airflow & Performance Notes
⚠️ No CFD analysis has been performed at this stage.
This is a Version 1 design focused on physical fit, routing efficiency, and real-world usability.
Initial testing confirms proper fit and clearance; airflow testing is ongoing.
Planned iterations may include:
- Optional check / flapper valve at the inlet
- Geometry refinements based on measured airflow and back-pressure
Project Status
- ✔ Physical fit validated
- ✔ Slim wall/window clearance confirmed
- ⏳ Full airflow characterization in progress
- ⏳ Final installation photos pending
This design will continue to evolve based on real-world testing and community feedback.
