Description

I have a 1991 Nissan D1 (hardbody) that had broken air vents due to age. I decided to make both the cover and the actual vent. The cover clips to the dampener but it is a snug fit to install, probably easier in warmer weather since it will soften the vinyl some. For the vent itself, I tried to give it 0.25 gap in between the moving parts that move the louvers up and down, but either my printer is not that precise or it is not enough of a gap.

Vent Cover: I would suggest printing the vent cover flat side down for a smoother finish and no supports will be needed.

Vent: I printed this with the adjustment handle facing up with supports to get a smooth finish. In the picture one is the original the other is printed, can you tell which is which?

I printed these in black PLA since it was more like a prototype, but I know it won't hold up to well in the heat. Now that I know it fits and looks pretty good I will print them again in ABS or PETG for more durability. I will post pictures of install if interested.

Thanks, and enjoy!

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.

FilamentUSD / printApplication notes
PLA$28.50Indoor prototypes; not a default material for hot vehicle interiors.
PETG$29.00General-purpose candidate; heat and creep need review.
ASA$32.50Candidate for UV exposure; verify temperature and geometry.
ABS$31.50Enclosed printing; review application and dimensions.
TPU$37.50Flexible designs only; not a substitute for rigid materials.
Nylon$37.50Moisture, tolerances and application require review.
PA-CF$42.50Filled 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.
