Description
After printing crazytiti's F30 F31 speaker adapter, I noticed the car-side holes didn't align with the holes on the adapter on my F22 2 series (the F30 speakers must be slightly larger). This new adapter has the correct speaker screw circle for the 2 series and presumably also the F87 M2.
To adapt crazytiti's design, I moved the bolt circle inward as well as slotted the mounting holes to match the design of the OEM speaker and added clearance around the bolt holes for the bolt heads.
This Thing is marked as a Work-In-Progress as I haven't printed and installed this yet to ensure it will fit my 2 series. I may have to add additional bolt head clearance to make sure the OEM speaker bolts will fit, but I don't see any other reason it shouldn't fit. This should also fit the rear parcel tray speakers, but I've yet to test that.
I've also included the .f3d file for easy modification.
Applications: F20, F21, F22, F23, F87

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.
