Designing your first car part from a blank screen can be tough.

So we created a spark plug wire holder design you can quickly modify that will help you learn the basics of automotive CAD design.

🎁 FREE Download: Use our premade spark plug wire holder to speed up your design with just a few clicks. The design features:

✅ Circular style clip to hold spark plug wires neatly in place
✅ Stronger, cleaner design than stock clips
✅ Editable file so you can customize it

Want to skip the guesswork and design your own parts in 1 day?

I took everything I learned from measuring, designing, and 3d printing and turned it into a 1-Day Car Parts Design Workshop.

Learn to go from idea → CAD → 3D printed part that survives in your car, without months of trial and error.

START SIMPLE

The best way to get started is with a very basic design. We picked a spark plug wire separator clip you can modify for your project car in just a few simple steps.

1. DOWNLOAD SHAPR3D

Designing your first car part doesn’t need to be complicated. Which is why you should download [Shapr3d here].

Shapr3d is by far one of the easiest and most powerful CAD software programs we’ve tried.

It even works with an iPAD and Apple pencil, but you can also download a desktop version too.

2. IMPORT THE FREE SHAPR3D FILE

The design has already been created, so all you have to do is download and import the design into Shapr3d with the import feature.

3. MEASURE YOUR PART

Grab a measuring tool like a caliper or ruler and start taking measurements of your spark plug wire clip.

4. MODIFY THE SIZE

Use the history tool in shapr3d on the right hand menu to modify the sketch size. You can adjust the length, width, or diameter of the circles.

If you want the spark plug wire holder to be thicker, you can also modify the height or by clicking the Extrusion in the history panel.

You can also modify the fillets to provide a tigher fit.

5. EXPORT AND PRINT THE DESIGN

Use the Shapr3d export feature to export the design to an STL file and add it to your 3d printing software to print.

💡 Note: The free version of Shapr3d exports in lower resolution. If the shape isn’t smooth enough, give the Shapr3d trial version a try.

…NEED A 3D PRINTER…

Use our [3d Printer and Filament selector here] to pick the best setup based on the part, budget, and size.

You can also send your part to a print on demand service like PCBway.com if you don’t have a 3d printer.

7. TEST FIT THE DESIGN

Here’s the design. Let’s check the fitment:

…IT FITS PERFECT…

If the size is slightly off you can go back to Shapr3D and adjust the scale using the history function.

But if you’re ready to start making more parts for your ride, we put everything together in a simple workshop below.
