Description

Simple box/tube for installing 10 cm speakers behind the seats in a Mazda Miata / MX-5 NB (don't know if NA looks the same).
It's secured using the original screws on either side, the ones with the plastic cone-thing.
Thus no drilling in the car needed. Though drilling is needed in the tube/tower for the speakers screws.
Should be noted if it's not clear from the pictures, my car has no soft-top, only hardtop.
There is not space for these if you still have a soft-top.

My speakers are 50 mm deep so I made the tower/tube 55 mm.
Yes, the speakers are small, but I had them so in they went.
Yes the tubes are ugly, I made the model in https://www.tinkercad.com/ and for some reason the smoothest you can get a cylinder is "64 sides".

I printed in cheap PLA, https://www.3dprima.com/se/filament/3d-prima-basic-pla-1-75mm-1-kg-grey/a-26002
Again, it's what I had on hand.

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.
