15 Best 3D Printed Parts for Toyota 4Runner Owners [All Generations]

The Toyota 4Runner has earned legendary status among off-road enthusiasts and daily drivers alike. From the boxy first-generation rigs of the 1980s to the capable 5th-gen models still dominating trails today, 4Runners have one thing in common: a passionate community that refuses to let discontinued parts or expensive dealer prices stop them from keeping their vehicles in top shape.

3D printing has revolutionized how 4Runner owners approach maintenance, customization, and restoration. Whether you're bringing a 1987 first-gen back to life or adding convenience features to your 2023, there's a growing library of printable parts designed specifically for Toyota's iconic SUV.

This guide covers the 15 most popular 3D printed parts for 4Runners, with generation-specific recommendations, material guidance, and resources to get you started.

4Runner Generation Quick Reference

Before diving into specific parts, here's a quick reference for 4Runner generations. Parts are rarely cross-compatible between generations, so knowing your chassis code is essential:

The 15 Most Popular 3D Printed 4Runner Parts

1. Cup Holder Inserts & Replacements

Without question, cup holders are the #1 most printed 4Runner part. Every generation has its own cup holder challenges—from the completely absent holders in early 1st-gen models to the oversized, loose-fitting factory designs in 4th and 5th gen vehicles that let your coffee dance around on every bump.

The 4Runner community has developed incredible cup holder solutions for every generation:

• 1st Gen (1984-1989): Console insert cup holders with phone slot—adding functionality that never existed from the factory
• 2nd Gen (1990-1995): Double cup holder inserts that fit the cubby hole in front of the armrest
• 3rd Gen (1996-2002): Late 3rd-gen console upgrades with dual holders and switch plates
• 4th Gen (2003-2009): Cup holder reducers for the oversized factory holders, plus phone mount combos
• 5th Gen (2010-2024): Cup holder inserts to prevent the notorious rubber liner issue (sticks to cups)

2. Phone Mounts & Cradles

Generic aftermarket phone mounts look out of place and often block vents or controls. 4Runner-specific 3D printed mounts integrate seamlessly with your dashboard:

• Dashboard clip mounts that attach to existing trim pieces
• Cup holder phone inserts that sacrifice one holder for a dedicated phone spot
• Vent-mounted holders with 4Runner-specific clip geometry
• MagSafe-compatible mounts for iPhone users
• Wireless charging cradles with custom 4Runner fitment

The 4th-gen has particularly popular combo designs that put a phone holder inside one cup holder while keeping the other functional—perfect for the trail.

3. Center Console Organizers & Drawers

The 4Runner's center console is cavernous but poorly organized. 3D printed organizers transform this dead space:

• 5th Gen cubby drawers: Slide-out trays that make the console cubby actually usable
• Coin holder inserts: Dedicated spots for toll change and parking meters
• Key/wallet organizers: Compartmentalized trays for daily carry items
• Under-seat organizers: Custom trays that maximize hidden storage

4. Switch Plates & Blank Delete Panels

Adding off-road lights, compressors, or other accessories? You need switch mounting solutions:

• 3rd Gen center console switch plates: Replace the awkward factory layout with clean Carling-style switch mounts
• 5th Gen blank delete panels: Replace unused switches with clean blanks or new switch cutouts
• A-pillar switch pods: Mount auxiliary switches without drilling your dash
• Overhead console switch panels: Add switches to the ceiling without permanent modification

The late 3rd gen switch plate is particularly popular—when Toyota added cup holders to the console in 1999+, many owners wanted to keep their switches accessible. 3D printed plates solve this perfectly.

5. HVAC Vent Clips & Louvers

Broken air conditioning vents are a common complaint across all 4Runner generations. The fragile louver mechanisms and mounting clips fail with age:

• 1st Gen mid-air vents: Complete louver assemblies for the dashboard
• Vent clip replacements: The small clips that hold vents in place
• Louver pivot pins: Tiny parts that often snap but are easy to print
• Defrost vent components: Hard-to-find pieces for older models

6. Armrest Components

4Runner armrests take a beating over time. The lid hinges break, the storage compartments crack, and the surfaces wear:

• 4th Gen armrest lid replacements: The factory lid is a notorious weak point
• Center console storage lid: 2003-2009 models often need new covers
• Hinge mechanisms: Small printed hinges to repair broken lids
• Armrest extension pads: Raise the armrest height for better ergonomics

7. Hitch Covers

A simple but satisfying print—custom hitch covers let you show off your 4Runner pride:

• Toyota logo covers: Clean OEM-style appearance
• Custom text/graphics: Trail names, club logos, or personal designs
• Functional covers: With integrated 5/8" pin holes or bottle openers
• Illuminated covers: LED-compatible designs for visibility

The standard 2" receiver hitch cover is one of the easiest 4Runner prints to start with—low material cost, simple geometry, and instant satisfaction.

8. Roof Rack Adapters & Accessories

Mounting third-party accessories to factory roof rails often requires adapters:

• Yakima round bar adapters: Connect Yakima crossbars to factory 4th gen rails
• Light bar mounting brackets: Attach LED bars to roof racks without drilling
• Awning mounts: Custom brackets for ARB, 23 Zero, or other awning brands
• Gear tie-down points: Add D-rings or tie-down loops to existing racks

Print in ASA or PA-CF for any load-bearing roof accessories—these parts experience UV exposure, weather, and mechanical stress.

9. Fog Light Covers & Brackets

The 4Runner community loves custom lighting. 3D printing enables:

• Fog light back covers: Protection for the back of aftermarket fog lights
• Ditch light brackets: Mount auxiliary lights at the base of the A-pillar
• Grille-mounted light brackets: Add small LED pods behind the grille
• Fog light delete covers: Clean blanks for when you remove factory fogs

10. Lift Gate & Tailgate Components

The 4Runner's rear lift gate has several plastic trim pieces that deteriorate:

• Lift gate reveal molding: The black plastic pieces on both sides of the rear window
• Hatch handle bezels: Trim around the external lift gate handle
• Interior cargo area clips: The small fasteners holding cargo panels in place
• Tailgate party accessories: Cup holders, phone mounts, and organizers for tailgating

The lift gate reveal moldings are expensive from Toyota and frequently requested in 4Runner forums. These are excellent candidates for 3D printing in weatherproof ASA.

11. Gauge Pods & Instrument Mounts

Overlanders and performance enthusiasts often add gauges for boost, EGT, oil pressure, or voltage monitoring:

• A-pillar gauge pods: 52mm or 60mm gauge mounts that clip to the A-pillar
• Dash-top pods: Surface-mounted gauge clusters
• Vent-integrated gauges: Replace unused vents with gauge mounts
• OBD2 display mounts: Custom holders for digital gauge displays

12. Fuse Box Covers & Engine Bay Accessories

The engine bay benefits from 3D printed organization and protection:

• Fuse box covers: Custom covers with labeling or improved sealing
• Relay holders: Add auxiliary relays for lighting or accessories
• Wire routing clips: Clean up aftermarket wiring installations
• Fluid reservoir brackets: Mount secondary reservoirs for off-road builds

13. Sun Visor Clips & Mirror Components

Small interior parts that break but cost too much to replace from Toyota:

• Sun visor mounting clips: The clip that holds the visor to the roof
• Vanity mirror covers: Replacement lids for the mirror light assembly
• Visor extension clips: Add a secondary visor for side sun protection
• Rear view mirror trim: Decorative covers for the mirror base

14. Door Handle Bezels & Interior Trim

Interior plastic trim degrades with UV exposure and age:

• Interior door handle bezels: The trim around interior door pulls
• Window switch surrounds: Replace cracked or faded switch panels
• Door panel clips: The hidden fasteners that hold door cards in place
• Grab handle mounts: Replace broken roof grab handle brackets

15. Trail & Off-Road Accessories

The 4Runner's off-road heritage inspires creative trail accessories:

• Fire extinguisher mounts: Secure mounting brackets for safety equipment
• First aid kit brackets: Keep emergency supplies accessible
• CB radio mounts: Custom brackets for communication equipment
• Recovery gear organizers: Tray systems for shackles, straps, and tools
• MOLLE panel adapters: Attach MOLLE accessories to 4Runner surfaces
