Description
The frame was designed by measuring the factory fresh air intake housing and modeled in CAD. It can be produced in two different ways:
Laser cut from plexiglass / acrylic sheets
3D printed directly from the included STL file
The filter media can be replaced easily by opening the frame and installing a new sheet material. You may use:
Range hood / aspirator filter material
HEPA sheet filter
Activated carbon filter sheet
Universal cabin filter media
Features:
Direct-fit style retrofit design
Reusable frame, replaceable filter media
STL file included for 3D printing
Suitable for DIY enthusiasts
Improves cabin air cleanliness
Recommended Materials:
PETG / ABS for heat resistance if 3D printing. PLA can deform in engine bay heat.
Vehicle Compatibility:
Mercedes-Benz W124 chassis (fitment may vary depending on HVAC box type and production year)

Print price estimates
Planning prices for one print, not a final quote. Defaults use a size allowance inferred from the part name, not a measured or sliced model. Filament suitability must be confirmed.
| Filament | USD / print | Application notes |
|---|---|---|
| PLA | $28.50 | Indoor prototypes; not a default material for hot vehicle interiors. |
| PETG | $29.00 | General-purpose candidate; heat and creep need review. |
| ASA | $32.50 | Candidate for UV exposure; verify temperature and geometry. |
| ABS | $31.50 | Enclosed printing; review application and dimensions. |
| TPU | $37.50 | Flexible designs only; not a substitute for rigid materials. |
| Nylon | $37.50 | Moisture, tolerances and application require review. |
| PA-CF | $42.50 | Filled nylon; abrasive filament and fit need review. |
Pricing assumptions and exclusions
USD: ($6 setup + $3 finishing + filament weight × assumed spool cost × 1.25 waste allowance + print hours × $2.50 × material time factor) ÷ 0.65. Rounded up to the next $0.50.
Assumed spool costs per kg: PLA $25, PETG $30, ASA $40, ABS $30, TPU $45, Nylon $65, PA-CF $95. Time factors: PLA/PETG 1.0, ASA/ABS 1.2, TPU 1.6, Nylon 1.4, PA-CF 1.5. These are proposed shop rates, not measured production costs.
Design work, test fitting, hardware, shipping and tax are additional where needed. Multi-file sets may need several prints. Use actual sliced weight and time when available. Final pricing is confirmed in writing.
