Interior

Spacer for mounting a 165 mm (6.5 inch) aftermarket speaker to the MiTo three-hole door pattern while clearing the window glass and door card. The creator reports perfect rear-door fit; the front mounting holes required slotting. The editable STEP file is archived, while the validated STL is supplied. Verify front/rear hole position before drilling.

Replacement plastic retaining tab for the interior door card, designed after the creator's originals broke. PETG is inferred for snap-fit toughness and cabin heat; nylon is an alternative. Confirm door-card retention and avoid obstructing side-impact equipment.

Replacement clip retaining the front windscreen-pillar upholstery. PETG is inferred for snap-fit toughness and cabin heat; nylon is a tougher alternative. Confirm trim retention without interfering with wiring or airbags.

Replacement small button for the rear window-lifter assembly. The creator identifies exact component number 71740195. PETG is inferred for repeated operation and snap-fit toughness; ABS or nylon are alternatives.

Replacement cover for the bolt inside an interior door lever. The creator redesigned the fragile original retaining teeth. PETG is inferred for snap-fit toughness and cabin heat; ABS or nylon are alternatives.

Front-door adapter for a 16.5 cm speaker, supplied as one quarter so four copies can be printed and bonded for each speaker. Confirm assembled diameter, bonding strength, screw pattern and window clearance. PETG is inferred for toughness; ABS is an alternative.

Spacer ring for installing a 16.5 or 17 cm speaker. Confirm speaker depth, screw pattern and window-glass clearance before assembly. PETG is inferred for vibration resistance and cabin heat; ABS is an alternative.

Two source-provided replacement lock variants for the boot-lid carpet access hatches used to reach the tail lamps. PETG is inferred for snap-fit toughness and repeated handling; ABS or nylon are alternatives.

Flexible insert mat for the interior door-handle recess. TPU is inferred for grip, quiet contact and easy removal; PETG is a rigid alternative only if flexibility is unnecessary.

Replacement driver-door button for controlling the rear windows. PETG is inferred for repeated pressing, snap-fit toughness and cabin heat; ABS or nylon are alternatives. Confirm free travel and switch return before installation.

Two replacement clip variants: standard size and a creator-provided version enlarged by five percent. Compare the original clip and use the matching variant. PETG is inferred for snap-fit toughness and cabin heat; nylon is a tougher alternative.

A leg adapter to use after market speakers in place of the original front speakers for our Alfa 147s

The old one broke, so I designed this to mirror the original Alfa Romeo 937 (147) window knob. I printed it in PETG for flexibility.

Replacement trim cover for the screw behind an interior door handle. The creator designed and fitted it for the Alfa Romeo GT, noting that its retaining clip is delicate. Print in PETG for cabin heat and improved clip toughness, remove supports carefully, and compare the retaining geometry with the original before installation.

Multipart spacer set for installing a 6.5-inch front-door speaker without modifying the door. Print one base plate and two copies of the spacer, as the creator specifies. Explicitly designed for Alfa Romeo 147 and 156 doors. PETG is inferred for cabin heat resistance and screw-clamping toughness; ABS is an alternative.

Replacement support bracket for the door tweeter on the Alfa Romeo Tipo 916 GTV. The creator designed it to replace the original bracket that commonly breaks with age; verify the speaker and door-trim attachment points before installation.

Replacement interior door-handle cover for Type 116 GTV models. The creator notes that the small retaining legs can remain fragile; inspect clip engagement and avoid forcing the cover during installation.

Flexible gasket for the exterior door handle of an Alfa Romeo Alfetta sedan. The creator printed it in TPU at 20 mm/s and notes that the current size squeezed on successfully but could possibly be slightly larger; test-seal against the handle and paintwork before final assembly.

Replacement retainer for the 90-degree end of a broken interior door-release cable. The creator redesigned and installed it in a Giulietta door mechanism. Use a tough material and verify reliable repeated release from inside and outside before returning the vehicle to service.

Reinforced replacement for a weak interior pull handle reverse-engineered from the original component. Use a tough, heat-resistant material, compare the mounting points with the original, and verify the handle is securely retained before use.

Adapter for mounting a standard tweeter on the original 145 tweeter mount. The creator glued the tweeter to the adapter and removed the front grille and bent the tweeter wire pins to fit the available space.

Printable left- and right-side map-pocket shells, back plate, and edge trims intended to be covered with vinyl; the back plate is made from 1–1.5 mm aluminium sheet.

Replacement covers for the interior door-handle screw openings.

Replacement push lugs for the window switches. The creator intentionally made them long so they can be trimmed to length.
