Creating a Custom Cybertruck Vault Shelf with 3D-Printed Brackets and Milwaukee Packout Wall Mounts
The Tesla Cybertruck’s vault provides a massive storage space, but maximizing its usability requires some creativity. I recently designed and installed a custom shelf in the vault using 3D-printed brackets, extruded aluminum, and Milwaukee Packout wall plates. Here’s how I did it and what I learned along the way. Why Build a Custom Shelf? While the aftermarket currently has a couple molle shelf options for the vault, I felt they were a bit pricey at around $500 and didn’t quite provide what I wanted. I was looking at a modular, durable, and efficient way to store tools and gear—enter the Milwaukee Packout system. My goal was to create a shelf that securely mounts Packout wall plates while keeping the vault’s floor space open for larger items. Materials Used The Build Process Step 1: Designing the 3D-Printed Brackets The key component of this build was the custom 3D-printed brackets that attach to the Cybertruck’s L-Track system. Instead of using bolts, I designed a wedge-fit mechanism with slots that securely engage with the L-Track, preventing movement. However, bolts can still be added for extra security if needed. Each bracket was also designed with slots for T-slot nuts and bolts, allowing easy mounting of the extruded aluminum frame. Step 2: Mounting the Extruded Aluminum For the shelf’s structure, I used 2040 extruded aluminum. Initially, I planned to mount it flat, but I found it had too much flex. Switching to a vertical orientation significantly improved rigidity. The aluminum was attached to the brackets using T-slot nuts and bolts, ensuring a strong, adjustable connection. This was the Aluminum Extrusion Hardware Accessories I purchased from Amazon. While the description stated “not easy to rust”, if I see any signs of corrosion I’ll look at getting a different set. Step 3: Installing the Milwaukee Packout Wall Plates With the aluminum frame securely in place, I mounted two Milwaukee Packout wall plates. These provide a rock-solid base for stacking Packout toolboxes, organizers, and storage bins, making it easy to customize my vault storage. Lessons Learned and Future Improvements Current Milwaukee Packout Cybertruck Setup These are the Milwaukee Packout cases I currently have. A 106 piece Milwaukee socket set, drill bit set, and a Packout case I currently store some of my Molle panel mounting accessories in. Final Thoughts One of the biggest advantages of this custom setup is its cost-effectiveness. Compared to aftermarket solutions, which can be quite expensive. If you have access to a 3D printer, this DIY approach with brackets and extruded aluminum was far more affordable while still offering durability and functionality. The modular design, durability, and Packout compatibility make it a game-changer for anyone looking to maximize their Cybertruck’s storage potential. If you’re considering a similar setup, 3D printing custom brackets combined with extruded aluminum and Packout mounts is a solid solution. We’re going to make a few small adjustments to the design, but will likely upload these brackets to one (or multiple) of the 3D file sharing sites such as MakerWorld. Stay tuned for future updates as I refine the design and test its weight capacity! Have Questions or Suggestions? Let me know in the comments! Would you build something similar in your Cybertruck?
