Description
This is a speaker adapter for a 1988 Volvo 740. The factory mounts are oval and this allows a 5.25'' (13cm) speaker to be used in the doors. It also allows the original cover to be put back in place.
Front and back doors are the same so it will work for both. Will probably fit other Volvos are this era too.
New screws that come with speakers to be used to mount to door and old screws from original speaker to be used to mount new speaker on adapter.
Note: You will more than likely have to modify the speaker mounting bracket.
Happy printing!

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.
