Mazda RX-7 Infini III FC3S 1989 STL 3D Print Model

The Mazda RX-7 Infini III FC3S 1989 is an iconic Japanese sports coupe powered by a twin-turbocharged rotary engine, here faithfully reproduced as a highly detailed 3D print model. The model includes two versions — one with open cabin and no glass for full interior visibility, and one with windowed/lights version — both featuring intricate BBS-style mesh wheels, a functioning hood scoop, rear spoiler, twin exhausts, and a fully detailed interior with steering wheel, seats, dashboard, and door panels. Designed for FDM or resin printing at any display scale, it is provided in STL format ready for slicing. The level of surface detail and separate component approach makes it ideal for scale modelers, collectors, and automotive enthusiasts.

Print settings

For best exterior surface quality, print main body panels with resin (MSLA/DLP) at 0.05 mm layer height; FDM printing at 0.1–0.15 mm with a 0.2 mm nozzle is also viable for larger scales. Orient the body shell with the roofline down to minimize visible layer lines on curved surfaces. Supports are recommended under the front bumper lip, side skirts, and rear diffuser area. Use 20–30% infill with a gyroid or honeycomb pattern for structural balance; PETG or ABS is preferred for larger assemblies, while PLA works well for display-only pieces.
