3D Printed Millennium Falcon Desk Organizer – Star Wars Inspired Workspace Upgrade

Here’s a fun project I put together: a Millennium Falcon desk organizer.

I’ve always liked the idea of mixing something practical with a touch of Star Wars, so I decided to turn the Falcon into a small organizer for everyday stuff—pens, pencils, USB drives, memory cards, and so on.

In this Instructable I’ll show you how I adapted the model and prepared it for 3D printing, step by step, so you can build your own version. It’s simple, useful, and of course, a bit of fan service for the desk.

You don’t need any special tools – just your 3D printer, filament, and your favorite slicing software:

Materials:

1. 3D printer (FDM) with a minimum print bed size of 200 × 200 mm
2. PLA filament (any color – I used light gray for a starship look)

Tools & Software:

1. Slicing software (e.g., Cura, PrusaSlicer, Bambu Studio)
2. Computer with USB/SD card for printer file transfer

A while ago, I modeled a Millennium Falcon in Blender, following this excellent tutorial: Millennium Falcon in Blender.

That project was purely for fun and to practice my 3D modeling skills.

For this new idea, I wanted to give that model a second life, transforming it into a functional desk organizer.

Since the modifications I had in mind involved adding compartments, pen holders, and USB stick slots, I decided to move the model into Tinkercad.

Tinkercad is a more beginner-friendly platform, which makes it easier to share the process with a wider audience.

This way, anyone, regardless of their 3D modeling experience, can follow along, make their own changes, and create a unique organizer inspired by the Millennium Falcon.

If you’d like to start from the same base model I used, you can download the original STL file right here in this step and play around with it before making your own modifications.

Before adding any organizer features, I wanted to make sure the base model would be easy to print (no supports, no tricky overhangs) just a clean print from start to finish.

The original Millennium Falcon model had several details and protrusions underneath, which looked great in a digital render but could cause problems on the printer bed.

To fix this, I removed the entire underside geometry and replaced it with a flat, continuous base.

This modification not only reduces print time and filament usage, but also ensures a strong, stable bottom surface, perfect for sitting securely on a desk without wobbling.

By starting with a “printer-friendly” version of the model, we avoid headaches later and guarantee that anyone following this project can print it successfully on almost any FDM 3D printer.

With the base model ready, it was time to transform the rear section of the Millennium Falcon into a multifunctional storage area.

I began by creating five cylindrical holders for pens, pencils, or markers. Each holder was made by combining a solid cylinder with a slightly smaller “hole” cylinder, which was subtracted to create a perfect hollow. From my testing, 2 cm of depth provides enough support to keep items upright.

Next, I modeled two microSD card slots using rectangular “hole” shapes, sized precisely for a snug fit. To make card removal easier, I added a small half-sphere cutout at the bottom edge of each slot — this little indentation gives your finger or nail the space needed to push or pull the card effortlessly.

Finally, I incorporated two USB stick mounts. These were designed as rectangular “hole” shapes matching the dimensions of a standard USB-A connector, so that a flash drive can “click” into place as if plugged into a port. This friction-fit design keeps the drives secure while still making them easy to remove.

By combining these three features — pen holders, microSD slots, and USB mounts — the entire rear section now serves as a compact, versatile storage hub.

This feature serves as an open storage compartment for miscellaneous items.

To create it, I cut out two triangular “hole” shapes that fit perfectly into the available space, placing one on each side. This subtraction generated two identical recessed compartments within the model.

For the base of each compartment, I designed a raised floor pattern consisting of evenly spaced horizontal bars. These ridges not only improve the visual appeal by giving the compartments a bold, mechanical look, but also help small objects stay in place rather than sliding around.

The result is a pair of stylish, functional compartments that add even more versatility to the organizer’s layout.

The front section of the Millennium Falcon organizer features six microSD card slots, arranged in two rows of three on either side.

Each slot was created using a rectangular “hole” shape, sized precisely to fit a standard microSD card snugly.

This symmetrical layout not only maximizes storage capacity but also keeps the front section visually balanced and organized.

With this addition, both the front and rear of the organizer now provide dedicated spaces for memory cards, pens, and USB sticks, turning the Millennium Falcon into a fully functional desk companion.

With all modifications complete, it’s time to prepare the model for a smooth and trouble-free print.

1. Group All Shapes – In Tinkercad, select all parts (the original model plus every added or subtracted shape) and group them into a single, unified piece. This ensures there are no floating geometries or hidden overlaps that could cause slicing issues.
2. Check for a Flat Base – Make sure the bottom surface of the organizer is perfectly flat. This will improve bed adhesion and prevent wobbling once printed.
3. Optimize for No Supports – Review all overhangs and angled surfaces. Since the design was adjusted to be “printer-friendly,” no supports should be necessary, which saves material and reduces post-processing work.
4. Export as STL – Once satisfied, export the model in STL format and it will be ready to import into your preferred slicer.

With these final preparations, your Millennium Falcon Desk Organizer is now ready for the printing stage. In the next step, we’ll cover the recommended print settings for best results.

Now that the model is fully prepared, it’s time to bring your Millennium Falcon Desk Organizer to life with 3D printing. Here are the recommended settings to ensure a clean and reliable print:

1. Material: PLA filament works best for this model due to its ease of use and minimal warping.
2. Layer Height: 0.12mm is recommended for better details but you can use 0.2mm
3. Infill: 15–20% is sufficient for a sturdy structure, as the design already has solid walls.
4. Supports: None required
5. Print Speed: 50–60 mm/s is a safe range for FDM printers.
6. Orientation: Print the model upright with the flat base on the print bed for maximum stability.

Once printed, remove the model carefully from the bed. All compartments, pen holders, and memory card/USB slots should be ready to use immediately.

Tip: If any small imperfections remain, a quick cleanup with a hobby knife or fine sandpaper can help, but most prints should come out ready to display and use as-is.

With the print finished and cleaned up, your Millennium Falcon Desk Organizer is ready to jump into action.

This is the most rewarding part: placing it on your desk, filling the compartments with pens, USB drives, memory cards, or any small essentials, and seeing the starship double as a functional tool.

Not only does it keep your workspace organized, but it also adds a unique touch of Star Wars flair that makes your desk stand out.

So why not fire up your printer and make your own Falcon? It’s a fun project, practical in everyday life, and a guaranteed conversation starter for any Star Wars fan.
