3D printing allows you to make everything, from decorative items to functional parts and objects, and this also includes propellers. In addition to the classic and traditional designs, models can be experimented with thanks to the freedom that 3D printing allows for.
In this article, we’re including some of the coolest models for those looking to fly higher in their 3D printing adventures and who want to have fun or just learn a little more about propellers.
Keep in mind that high RPMs can pose a considerable risk to weaker materials and structurally weak designs or imperfections, so remember to exercise caution and use strong materials. Should you not have your material of choice around or if your 3D printer isn’t up to task, you can always check out Craftcloud by All3DP.
And if you’re looking for a more specific or custom design, you can also try to create your own propeller with automatic tools such as the Ultimate Toroidal Propeller Generator or the B-Series Propeller Generator.
Now let’s dive into our list!
Toroidal Propellers
This design is a departure from the norm by combining a high-speed launch mechanism with beautiful toroidal propellers. Compared to propellers with blades, toroidal propellers are significantly quieter because they don’t cause as much vortex turbulence, and in many cases they can also be more efficient in both air and water.
When it comes to this model, the planetary gearbox launches a toroidal ring, which you can see in action. All the parts that make up the design are 100% 3D printed, and, depending on whether you change any of the default settings or not, printing time should be around 7 hours. The designer includes detailed printing tips, as well as as well as an illustrated and detailed step-by-step guide to help you assemble everything with no issue. You’ll need to take extra care to fit the gears and lubricate them to reduce friction.

Contra-rotating Coaxial Propeller
Whether you’re a mechanics student or are merely curious, if you have any interest in propellers, you may have seen something like this. This design consists or contra-rotating propellers, two propellers rotating in opposite directions coaxially (on the same axis). These shouldn’t be confused with counter-rotating propellers, such as those mounted on either side of an aircraft wing.
The system uses bevel gears and is a very creative and simple demonstration that doesn’t require bearings or additional parts other than 3D printed ones. To lock the handle well, the designer recommends using a piece of 1.75-mm filament – if you’re in doubt about any part of the assembly, be sure to check out the maker’s video. The stand is optional but makes this even more eye-catching if you’re going for a decoration piece.

Variable Pitch Propeller
Based on a 1935 patent by Robert Stanley, this propeller offers 3D printing enthusiasts the perfect combination of technical challenge and fun. The model has two handles, one that works as the motor crank, and the other adjusts the pitch setting of the propeller blades. With patience and attention to detail, this model becomes not only an educational project, but also an impressive piece of mechanical engineering for any 3D printing enthusiast.
All parts were designed to be printed in PLA with 0.2-mm layer height, and there’s no additional hardware needed to put everything together. Because of how all the different parts need to be assembled, you might benefit from ensuring that your printer is well-calibrated before you get started. Feedback from users highlights that tolerances are tight, which is why some share additional tips on getting the setup running smoothly.

Paper Airplane Propeller
When your imagination and creativity are already in full swing, all that’s missing is a little extra boost, and for that, there’s nothing better than a 3D printed propeller.
With a printer, you can make a system that’s light and practical enough to make your paper airplane take off, but pay attention to the details, as it’s necessary to balance and define the center of mass for it to work properly.
To replicate this simple but effect model, keep in mind to enable a raft and supports, and the maker suggests using a 0.2-mm layer height with 100% infill. Even though the comments note that the airplane might be hanging from a string in the video, this model has already been downloaded more than 36,000 times and a few makes have been shared. Users agree that it’s a creative idea even if it’s not necessarily as shown, and that it can be improved with other materials and design adjustments. Do you accept the challenge?

Boat Jet Propeller
The versatility of 3D printing here shows once again that, in addition to colorful things, it’s possible to make functional pieces. Different types of propellers can be combined with motors for different setups. Here, the propeller is integrated inside the boat, making this little vessel glide over the water with great agility. This is an excellent opportunity to make a complete and fun project!
You’ll need to purchase the boat files from Cults, but the 20-mm 3-blade propeller model is free. The boat is waterproof and designed to automatically turn itself over when the propeller is activated if it capsizes. And for guidance, in addition to the BOM shared on Cults, the different videos include a thorough guide on the electronics side of things. Plus, you can see how fast and agile this RC jet boat can be!
