Description

My 2004 RX-8's climate control fan knob broke right on its stem. Cost of a new one is like fifty bucks! Gluing it back together is difficult because of the small surfaces and the fact that it's HDPE. So I made this little adapter that uses a friction fit on the remaining bits to re-create the necessary mounting hardware. It may fit other years, not sure.

Print instructions

Here's an attempt at a step-by-step. Watch my YouTube video to get a slightly better idea of what's going on: http://youtu.be/Ira08ukeK8A

1) You need to clean up the remaining bits of the knob's stem (or stalk, whatever you wanna call it). Look down the D-shaft. You'll notice a small X inside the D-shaft. Trim the D-shaft down flush with that X.
2) Print this out. I used 0.4 wall, 0.4 top/bottom, external supports, and 15% infill on Cura. I'd recommend using 0.6 wall/top/bottom if I were to re-print this; my print has gaps in the top layer as you can see.
3) Go to your car. Push the print onto the shaft.
4) Line up the knob and push it onto the print.
5) Enjoy your newfound control over the fan!

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$21.50Indoor prototypes; not a default material for hot vehicle interiors.
PETG$21.50General-purpose candidate; heat and creep need review.
ASA$23.50Candidate for UV exposure; verify temperature and geometry.
ABS$22.50Enclosed printing; review application and dimensions.
TPU$26.00Flexible designs only; not a substitute for rigid materials.
Nylon$26.00Moisture, tolerances and application require review.
PA-CF$28.00Filled 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.
