Triumph Spitfire / TR5 / TR6: 52 mm gauge pod for the dash-top ashtray – no drilling

Description

For the Triumph Spitfire (Mk3, Mk4, 1500) and the TR5/TR6: the pod replaces the ashtray on top of the dashboard and holds one 52 mm gauge, e.g. oil temperature or oil pressure. No hole in the wooden dash.

• A hollow foot with crush ribs clamps in the ashtray opening, a flange rests on the dash pad. Nothing is drilled, the ashtray can go back at any time.
• The gauge stands at 75° tilt and is turned 20° toward the driver: variants for right-hand and left-hand drive.
• The cable runs through the hollow stand and the foot down behind the dashboard.
• Prints without supports.

Fit: the opening (106.2 × 41 mm) is taken from two freely published ashtray inserts; according to their makers it is the same on the Spitfire, TR5 and TR6. Our part is not yet tested in a car.

File the crush ribs if needed; too loose: add felt tape to the foot. Check the +0.4 mm bore with the test ring.

Dimensions

Dimensions of the default variant in print orientation.

Material and temperature

Location in direct sun: print in ASA or ABS only. A dashboard reaches about 69 °C on average after one hour in the sun, with peaks up to 89 °C. ASA only softens at around 108 °C and is UV resistant. PETG and PLA will warp here.

Print orientation: Front face on the bed, cup pointing up; flange and foot stand vertical.

Safety notice

The pod sits centrally on top of the dashboard, clear of the steering wheel; these cars have no airbags. It must not disturb the view through the windscreen – if in doubt choose the 52 mm variant. Use ASA: the dash pad gets hot in the sun. Check it is secure before driving. Install at your own risk. Never mount in an airbag deployment zone, never cover controls, never restrict the view. Follow the material and temperature advice. Add-ons may affect the type approval of the vehicle (§ 19 StVZO in Germany); keep edges in the head and knee area rounded (UN Regulation No. 21).

Not an original part. No affiliation with the vehicle manufacturers named; make and model names only indicate fitment.
