3D Printed Car Accessories: Organize Your Ride for Less

The hum of a 3D printer is becoming increasingly common, not just in maker spaces and workshops, but in homes across the country. What started as a niche hobby has blossomed into a practical tool for customization and problem-solving, and increasingly, for automotive enthusiasts. As the pace of life accelerates, and vehicles become mobile extensions of our daily routines, the need for organization within those spaces grows. It’s a trend that’s particularly relevant here in Austin, Texas, where a booming population and a love for road trips mean cars are often packed to the brim. The good news is, a growing number of readily available 3D printable designs are offering solutions to common car clutter challenges.

The beauty of 3D printing lies in its ability to address specific needs. Unlike mass-produced organizers, these designs can be tailored to fit the unique contours of a vehicle’s interior, maximizing space and functionality. This is a significant shift from the “one-size-fits-all” approach of traditional automotive accessories. The rise of platforms like MakerWorld and Printables.com has democratized access to these designs, allowing anyone with a printer to create custom solutions. It’s a trend that aligns perfectly with Austin’s DIY spirit and its thriving tech community. The University of Texas at Austin’s engineering programs, for example, are increasingly incorporating 3D printing into their curriculum, fostering a novel generation of designers and innovators.

Car Trunk Cargo Holders

The trunk, or boot as it’s known in some parts of the world, is often a black hole for loose items. Groceries, emergency kits, sports equipment – they all tend to migrate and become a jumbled mess. Jonas, a designer on MakerWorld, offers a solution with his heavy-duty car trunk organizer and cargo holder. These relatively simple, T-shaped tabs utilize Velcro or grip tape to secure cargo in place, preventing items from shifting during transit. The design comes in two sizes, catering to both lighter and heavier loads. The popularity of this design is evident in its impressive stats: 121 likes, 317 downloads, and 175 makes, with a stellar 4.9-star rating. Users consistently praise its durability and effectiveness, noting how it prevents toolboxes and other items from rolling around. While ABS is the recommended filament, ASA and PETG have also proven successful.

Velcro Car Storage Pocket

Limited in-car storage for small essentials – phones, pens, sunglasses – is a common frustration. PrintedGuy on Printables.com addresses this with a Velcro car organizer pocket. This design provides a dedicated space for frequently used items, freeing up cupholders and preventing clutter. The pocket attaches to carpeted surfaces using Velcro, offering flexibility in placement. With nearly 1,300 likes, 2,300 downloads, and 17 makes, this design has resonated with a large audience. Reviews highlight the ease of installation and the effectiveness of the Velcro attachment. PLA and PETG are commonly used filaments for this print, and the design is compatible with a 10×8 centimeter piece of Velcro.

Car Seat Hooks

Keeping the floor and seats clear is crucial for passenger comfort. Car seat hooks offer a simple yet effective solution for hanging bags, trash containers, or even clothing. Khpa on MakerWorld has created a series of organization hook designs that attach to the back of a seat’s headrest. Variants include shorter hooks for smaller seats and thicker versions for heavier loads. This creation boasts almost 6,000 downloads, 4,500 prints, and 2,700 likes. Users report that the hooks are easy to print, sturdy, and capable of holding a significant amount of weight. Some even use them to hold tablets for rear-seat entertainment. PETG or ABS are recommended filaments, as PLA can deform in high temperatures – a particularly important consideration during those hot Austin summers. The creator also notes a distinction between the closed-hole variant, intended for permanent use, and the open J-hook design.

Cup Holder Coin Holder and Sorter

Loose change is a perennial car clutter culprit. Sairae on MakerWorld offers a solution with a cup holder organizer featuring multiple slots for different coin sizes, as well as compartments for pens, napkins, and other small items. This design has garnered over 1,300 likes, 1,700 saves, and 1,300 prints. Users praise its perfect fit in standard cupholders and the easy accessibility of coins. PETG is the preferred filament for this project, and the design is specifically tailored to United States coinage.

Navigating the Local Landscape: 3D Printing Resources in Austin

Given my background in materials science and a keen interest in the maker movement, I’ve observed firsthand the growing demand for these types of solutions. If this trend impacts you here in Austin, and you’re looking to leverage 3D printing for automotive organization, here are three types of local professionals you should consider consulting:

3D Printing Service Bureaus

If you don’t own a 3D printer, or if you require specialized materials or large-scale production, a local service bureau can handle the printing for you. Glance for bureaus that offer a range of filament options (PETG, ABS, ASA) and have experience with automotive-grade materials. Prioritize those with quick turnaround times and competitive pricing.

Automotive Detailing Specialists with 3D Printing Knowledge

Some detailing shops are beginning to integrate 3D printing into their services, offering custom organizers and accessories tailored to specific vehicles. Seek out shops that advertise this capability and can provide design consultation services. They can help you visualize how these organizers will fit into your car’s interior.

Automotive Electrical and Electronics Technicians

For more advanced projects, such as integrating 3D-printed components with existing car electronics (e.g., custom phone mounts with charging capabilities), you’ll need the expertise of a qualified technician. Ensure they have experience with automotive wiring and safety standards. The Austin Community College Automotive Technology program is a good place to start your search.
