12 Must-Print 3D Parts for El Camino Owners [1959-1987 Guide]

The Chevrolet El Camino—part car, part pickup, entirely iconic. Whether you're restoring a 1970 SS 454 or keeping your daily driver 1987 running strong, 3D printing is revolutionizing how El Camino owners tackle the "unobtainium" parts problem.

From 1959 to 1987, Chevy built five generations of the El Camino, and each one shares a common challenge: finding replacement parts. The good news? Many interior and trim components are perfect candidates for 3D printing—and they often share compatibility with the Chevelle, expanding your options even further.

Let's explore the 12 most popular 3D printed parts for El Camino owners, complete with material recommendations, where to find STL files, and what to watch out for.

Quick Reference: El Camino Generations

Before diving into parts, here's a quick breakdown of El Camino generations and their Chevelle/A-body compatibility:

12 Must-Print 3D Parts for El Camino Owners

1. Cup Holder Inserts (Console-Mounted)

Classic El Caminos weren't designed for modern 20-oz tumblers. The #1 most printed part for El Camino owners is a cup holder solution—whether it's an insert for the console, an armrest-mounted design, or a transmission hump holder.

For 1968-1972 models with the optional center console, the console cavity can accommodate custom cup holders that don't destroy the original look. Several makers on Etsy offer both STL files and finished prints.

• Best Material: ASA or ABS (heat resistant)
• Difficulty: Easy—simple geometry
• Cost Savings: $40-80 vs custom fabrication

2. HVAC Vent Clips and Louvers

Those fragile plastic vent louvers on 1968-1972 models are notorious for breaking. The little plastic clips that hold them in place? Even worse. This is where 3D printing truly shines—you can print spares and keep extras in the glovebox.

The key is using ASA filament for UV and heat resistance. Dashboard temperatures can exceed 150°F (65°C) in summer, and PETG will soften while PLA will warp.

3. Radio/Stereo Bezels

Swapping a vintage AM radio for a modern Bluetooth head unit? You'll need an adapter bezel. OEM-style bezels for DIN stereo conversions are wildly overpriced when they're even available—often $100+ for injection-molded plastic.

3D printed alternatives let you create the exact fit you need. Many community members have shared designs that accommodate single-DIN and double-DIN units while maintaining the period-correct appearance.

• Best Material: ASA (matte finish, UV stable)
• Print Time: 6-10 hours
• Post-Processing: Light sanding, paint to match interior

4. Shift Knob Adapters

The El Camino came with various shift knob thread patterns depending on year and transmission. Most automatic column shifters use different patterns than manual floor shifters (Muncie, Saginaw, T-5, T-56).

3D printed adapters let you use any aftermarket knob with your specific transmission. Print with PA-CF (carbon fiber nylon) for maximum durability under constant use.

5. Console Lid Hinges and Latches

The center console on 1968-1972 El Caminos (shared with Chevelle) features hinges and latches that become brittle over 50+ years. Metal replacements exist but are expensive; 3D printed versions work well for lightly-used consoles.

For high-use applications, consider printing with Nylon (PA) or PA-CF for the extra impact resistance. PETG is acceptable if the console isn't used as a leaning post.

6. Ashtray Delete Panels

Not everyone wants a functional ashtray in 2026. Converting the ashtray space into a phone holder, small storage tray, or USB charging station is a popular modification. 3D printing makes this conversion reversible—you can always reinstall the original ashtray if you sell the car to a purist.

• Phone holder with wireless charging pad cutout
• Storage tray with felt lining
• USB-C/12V power outlet panel
• Gauge pod for boost/AFR/oil pressure

7. Window Crank Handle Spacers

The window crank spacers (between the handle and door panel) crack and disintegrate over time. These are small, simple prints that can be knocked out in under an hour—and you should print several spares while you're at it.

This is an excellent first 3D printing project for El Camino owners new to the hobby. The geometry is simple, tolerances are forgiving, and success is nearly guaranteed.

8. Tailgate Latch Components

The El Camino's tailgate mechanism includes several plastic and fiber components that wear out. While metal parts should remain metal, the bushings and spacers are excellent candidates for 3D printing.

For exterior and bed applications, use ASA for UV resistance. Nylon (PA) or PA-CF provides superior wear resistance if the part sees frequent cycling.

9. Sun Visor Brackets and Clips

Sun visors on 1968-1972 models hang by plastic pivot brackets that crack from age and UV exposure. NOS replacements are rare; reproductions vary in quality. 3D printed versions can be made from ASA and painted to match the headliner.

The mounting holes and pivot dimensions are documented by the El Camino community, making it straightforward to design or find existing STL files.

10. Door Panel Clips and Retainers

Every El Camino owner has experienced the frustration of reinstalling door panels only to have clips break. These OEM clips were designed for one-time installation—not the multiple removals required during restoration.

3D printed replacements in Nylon (PA) can survive repeated installations. Print extras—you'll need them for the inevitable future panel removal.

11. Glove Box Door Components

The glove box door on 1968-1972 models uses plastic bushings and catches that deteriorate. The door itself is often warped from decades of use, and the latch mechanism may need rebuilt components.

3D printing allows you to recreate these small but critical parts without hunting through swap meets or paying premium prices for NOS pieces.

12. Custom Emblems and Badges

Whether you're replacing a faded SS badge or creating a custom "El Camino" script, 3D printing opens creative possibilities. Print the base in ASA, then finish with automotive primer and chrome or color-matched paint.

For truly authentic chrome appearance, consider printing a master and having it plated—or use the 3D print as a pattern for casting in metal.

Printer Recommendations for El Camino Parts

You don't need an industrial printer to make El Camino parts. Here's what works at each budget level:

Safety: What NOT to 3D Print

While 3D printing is excellent for interior trim and accessories, some parts should never be printed:

Stick to interior trim, convenience items, and cosmetic parts. Leave safety-critical components to proper engineering materials and manufacturing processes.

Getting Started: Your First El Camino Print

New to 3D printing? Here's the recommended progression:

1. Start simple: Window crank spacers or door panel clips
2. Learn materials: Print the same part in PETG and ASA—feel the difference
3. Tackle a project: Cup holder insert or ashtray delete panel
4. Design your own: Measure a broken part, model it in TinkerCAD or Fusion 360
5. Share with the community: Post your design on Printables or the El Camino forums
