I printed three of these on my Ender 3 Pro, one using 0.8mm gap, one using 0.6mm gap, and one using 0.4mm gap. I kept the 2mm the same on all three. In my opinion, the 0.8mm is a bit loose and the 0.4mm is a bit tight. The 0.6mm gap set of rings works the best. Thanks for this video!
thanks i also found the .8 gap to be a bit loose after i modeled it via blender so i came back to this comment to see what you'd said and this is good info
Did you print it also? And did it work? I imagine that holding the arc the same would decrease the space between the Rings at the outer rings when you turn them. If not that would be great!
i'm finding when i scale it up to seven rings the outer rings don't rotate , i think this is a downside of doing this method where they all have the same slope , because they don't orbit at the same ratio around the center they get caught up as you get further out. keen to find a way around this tho
basically it's moved over to create the shell closest to the middle , so it's half of the center circle's diameter plus the spacing gap which means he subtracted 5 to move it into position then add 0.8 to create the gap , in his example
This is a great explanation. I've found myself referencing back to it now on multiple occasions...
Brilliant! Been struggling with some naive attempts but this is a very clever way to do it. Thanks for taking time to share it. :-)

This is nice but how would you do it with more complex shapes? Like a heart?

nice video, if you wanted the sphere to be flat on the top and bottom side how would you do that?
I would create a sketch that shows the 2D profile of what you want and revolve it around the central axis.

Awesome. I’ll be doing this one.
Can I resize it?
How to extract stl? Theres6 bodies. Do I combine join?
Yes, you can do a temporary join operation to combine them into a single body to export to an STL.
The center has adhesion problem. Tried twice. Finally printed without center no problem
Amazing. I know you can print this. I am just trying to learn 360 and was able to follow along but have no idea what I just did. lol
Perfect!
Great video :) Why 4.2 as the starting distance on the left? Is there math there or just a number that you liked :)

Nice Bro
Very helpful
