Jeep Accessories: 5 Things You Can 3D Print

Instead of spending money on overpriced Jeep accessories, you can 3D print five practical items yourself: a phone mount, a cup holder insert, a grab handle cover, a tailgate table clip, and a storage organizer. These prints cost pennies in filament compared to retail prices, and they are custom-fit to your specific Jeep model. Below is a detailed guide on why 3D printing is a smart alternative, what to print, how to choose materials, and what to avoid.

Why 3D Printing Beats Buying Accessories

The aftermarket Jeep accessory market is huge, but many items are simple plastic parts with a big markup. A basic phone mount might cost $30–$50; printing the same design costs about $1–$3 in filament. You also get the advantage of customization—you can adjust the size, add your name, or match the interior color. Plus, if a part breaks, you can print a replacement in a few hours instead of waiting for shipping.

However, 3D printing is not always better. For load-bearing or safety-critical parts (like tow hooks or roof racks), buy professionally engineered accessories. But for interior convenience items, printing is often stronger and more durable than you might expect, especially if you use the right material.

What You Need to Start

To print Jeep accessories, you need a 3D printer (FDM/FFF type is fine), filament (PETG or ABS are best for automotive use), and a basic CAD program or access to online model repositories. Many free Jeep-specific models exist, but you can also design your own using free software like Tinkercad or Fusion 360 (personal license).

• Printer: Any 200mm x 200mm build plate is large enough for most accessories.
• Filament: PETG is a great balance of strength, heat resistance, and ease of printing. ABS is more heat-resistant but warps and smells. PLA is easy but deforms in a hot car.
• Nozzle: 0.4mm standard is fine; 0.6mm for faster prints.

5 Great Jeep Accessories to Print

1. Phone Mount (Dashboard or Vent)

A custom phone mount that clips onto the dashboard or air vent is one of the most useful prints. You can design it to fit your exact phone case and the specific contours of your Jeep’s interior. Print with PETG for heat resistance. Add a ball joint for adjustability. This is a perfect first project.

2. Cup Holder Insert

Jeep cup holders often don’t fit large tumblers or thermoses. A 3D-printed insert can adapt the holder to any cup size, or add a divider to hold two smaller cups. This is a simple print that takes less than an hour and uses very little filament. It also prevents spills on bumpy trails.

3. Grab Handle Cover

The factory grab handles on Jeeps can feel thin or slippery. Print a cover that slides over the handle, adding texture and grip. You can print it in a rubber-like filament (TPU) for a soft feel, or PETG for a rigid cover. This is a comfort upgrade that also protects the handle from wear.

4. Tailgate Table Clip

Many Jeeps have a tailgate table, but the clips that hold it in place break or get lost. A 3D-printed replacement clip is a cheap fix. You can also print a new clip that holds a cutting board or a small storage tray. This uses a small amount of filament and is a great functional print.

5. Storage Organizer (Center Console or Glovebox)

Design a custom insert for your center console or glovebox to hold pens, sunglasses, coins, or tools. This keeps items from sliding around on trails. You can make it fit perfectly around existing features. Print in PETG or ABS for durability.

How to Choose the Right Filament

Filament choice is critical for Jeep accessories because the interior gets very hot in summer and cold in winter. Here’s a quick guide:

• PLA: Cheap and easy, but softens at ~60°C (140°F). Not recommended for any part left in a closed car.
• PETG: Good heat resistance (up to ~80°C/176°F), strong, and easy to print. Best all-around choice.
• ABS/ASA: Higher heat resistance (up to ~100°C/212°F) and UV resistant (ASA especially). But requires a heated bed and enclosed printer to avoid warping.
• TPU: Flexible, great for gaskets or grips, but harder to print and not for structural parts.

For most interior parts, PETG is the sweet spot. For exterior parts (like a badge or a vent cover), use ASA for UV resistance.

Common Problems and How to Avoid Them

3D printing has a learning curve. Here are typical issues and fixes:

• Warping: Especially with ABS. Use a heated bed (100°C) and an enclosure. PETG warps less.
• Layer adhesion: If parts break along layer lines, increase nozzle temperature and reduce layer height (0.2mm or less).
• Heat deformation: PLA will sag in a hot car. Use PETG or ABS.
• Fit issues: Print a small test piece first to check tolerances. Adjust the model by 0.2–0.4mm if it’s too tight.

Cost Comparison: Printing vs. Buying

Let’s break down the cost for a typical phone mount:

• Buying: $25–$50 for a branded mount.
• Printing: ~50g of PETG filament, which costs about $1–$2 (bulk spool). Plus a few cents of electricity.

Even if you factor in the price of a 3D printer ($200–$500), you break even after printing a handful of accessories. And you can print infinite variations.

Safety and Durability Considerations

While 3D-printed parts are fine for interior accessories, never print anything that is safety-critical: tow hooks, roof rack mounts, or anything that holds heavy loads over passengers. Also, be careful with parts near airbags—don’t mount anything on the dashboard that could become a projectile in an accident. For exterior parts, use UV-resistant materials (ASA) and consider adding a coat of UV-resistant spray paint.

Also, regular PLA is biodegradable and will degrade in sunlight and heat. Stick with PETG or ASA for anything that stays in the car.

Frequently Asked Questions

Do I need a 3D printer to do this?

Yes, you need access to a 3D printer. If you don’t own one, check local libraries or makerspaces—many offer printing services for a small fee. You can also order prints online from service bureaus, but that reduces the cost savings.

What is the best filament for Jeep interiors?

PETG is the best overall for interior parts because it handles heat well, is strong, and is easy to print. For parts exposed to direct sunlight, use ASA for UV resistance.

Can I print parts that are as strong as factory ones?

For non-structural parts, yes. With proper infill (50–80%) and wall thickness, printed parts can be very strong. But for load-bearing or safety parts, factory parts are engineered and tested—don’t replace those.

Where can I find free Jeep accessory models?

Websites like Thingiverse, Printables, and MyMiniFactory have many free Jeep-specific models. Search for your Jeep model and the part name. Always check the comments for fitment feedback.

How long does it take to print a typical accessory?

A cup holder insert takes about 1–2 hours. A phone mount might take 3–5 hours. Larger items like a storage organizer can take 8–12 hours. You can speed up by using a larger nozzle (0.6mm) and thicker layers.

Will a 3D-printed part melt in a hot car?

PLA will soften and deform at temperatures above 60°C (140°F), which is common in a closed car in summer. PETG and ABS are safe up to 80–100°C (176–212°F), so they won’t melt in normal conditions.
