- In this video I show how I design those spiraly "impossible" passthrough objects for 3d printing using Fusion 360.
Please feel free to share any feedback in the comments.

Great video! I’m still learning Fusion and this was very helpful!
Hi, one doesn't have to dothe sweep with a spiral. Just have a line in the center, perpendicular to the base. Sweep along that line and make a rotation as you like.
Huh, somehow I must always have overlooked the twist parameter. Thanks!
Great video. Thanks
Thank you so much, can you search and make tutorial about " Making of 'Liam F1 Wind Turbine' " in Fusion 360, it's so hard to me, please !
Can you record the animation ? Thats neet.
Excellent tutorial. I have been wanting to make one of these, but didn't know where to start. Printing my first one now. Thank you!
I genuinely enjoy how you challenge modeling with this software. this one was fun to make and print.
Great video, I have printed a lot of these over the past few weeks, now I want try my hand and making one in fusion!
How do you make the ball shapes in fusion?
What kind of ball shapes do you mean?
Thanks so much, this helped so much!
Great tutorial! I managed to make the one with my Bamboo X1 following your steps!
This was very helpful for me figuring out a completely different design challenge, but the process worked perfectly.
Your amazing threads videos helped me finish a project recently, thank you! Now I have more confidence to experiment with this technique!
Incredible video
Thank you so much!
Wow! great tutorial!
Finally 👏🏻👏🏻
What’s the print settings to succeed with those very small overhang parts
Overhangs are usually not an issue with these geometries. Just dont go too fast and avoid blobs, eh at the seams. If the outer part reconnects in the top section many use tree supports, but even these should not be strictly necessary.
This is over complicated for this model. You can simply start with a sketch on the top plane that has 1 fin profile within a circle. Then add a vertical line at the origin and use the sweep command with a twist that follows the vertical line. After that you can extrude the original circle sketch with a taper angle to form a cone. Shell the cone and then use the outer surface to split the spiral you just made. Then use the spiral to split the cone and add tolerance on all faces of the spiral with the offset command. Done.
Yeah, thanks for the input, I somehow missed that sweep has the twist parameter 😬. Based on how the sweeping is implemented, I had good reasons to avoid offset and patterning the solid. Generally, I prefer working with solid booleans for such „partitions“.
Came here to make that exact same comment: sweep'n twist.
Did the offset directly on the initial sketch, like your 2nd attempt. so I can extude this thin surface to split the cone into 2 parts
Did the circular pattern cut in the Solid environement, not in the sketch (less processing stress on fusion: as a rule of thumb, it's always better to do patterns, filets and chamfers on 3D objects instead of in the 2D sketches)
That shows one thing: in 3D design, there are many many ways to reach the same result. The real art is to chose the simplest, most flexible and safets path
Yes it is. I use slot oval. Pattern. Sweep. Combine. Offsets of course. bout it.
