Nice.

I created a computer model similar to Buckminster Fuller's Fly's Eye dome. But, instead of basing it on a 3V class-I geodesic, I based mine on a 4V class-II.  There are 3 unique panels. Two of the panels are mirrors of each other.

It would be cool to 3D print small copies of the 3 panel shapes.  Then I would create plaster copies of those from silicone molds.  And, finally, I would connect them together to make a Fly's Eye dome model.

I'm going to forward this discussion to John Warren, who worked on fly's eye domes with Bucky.

nice work

I wonder if the form of a perforated sphere might be strengthened by transitioning the spherical surface into a curved collar around each perforation with a smooth compound curve. The diameter of each perforation being determined by the size of a circle touching the spherical surface centred at the intersection between two planes tangential to the sphere and perpendicular to the two closest vertices.

Attached is a copy of my methodology and a model very much the same as Rob Clark's produced from it.

John Kuhtik is another man to contact about fly's eye. Most helpful.

Our methods are very similar. In the images below, you can see the steps I used to create my model. I modified the underlying polyhedron so that all the red faces were identical, thus requiring only 3 unique panels.

I attached a .skp file in my last posting as well as an overview of the process I used neglecting those who do not have Sketchup. Excuse my omission.

It is not that different to Rob's except it is made with four pieces. My interest is in the surface form and the eye detail, expecting that a smooth compound curve around each perforation would bolster the strength of the whole sphere.

Hi, I'm looking for a way to build a geodesic dome for a science project. We've just built a 3D printer then printed a cnc machine and looking for a pattern to cnc cut a hemisphere, can anyone provide a cnc pattern for this?

Regards,

Derek

Nice! Follows Bucky's mantra of "doing more with less". Now, someone or some group needs to build one. :)
