Icosahedron Fuller projection globe

#1

The first project of the year is an icosahedron Fuller projection globe with 3D printed corners and Glowforge scored and cut panels.

Kewl! Did you design your corners? :sunglasses::+1:


#3

Yes I did. I wanted to go with a 2 piece threaded solution without glue, but the size was to small for the threads to print. So this version uses a bit of glue. The corners of the panels interlock with the 3D printed corners with a 3D printed cap that’s glued on.


#4

That is really neat! I’d love to see a version where the corners were made on a Glowforge. I suppose they would have to be redesigned, or would stick out, or something.


#5

Perhaps something like this?

Thanks for posting that! Once I saw this thread I started thinking about a way to do this 100% on the GF. My thought was to build a frame that I would glue the map pieces to, but I haven’t had time to fully think through the problem. This might be a better solution in any case.


#7

I was thinking of adding hooks to the back of each face and using dental elastics to provide tension to hold it together when I ran across this one. It might even be possible to trim the tabs and pocket-cut(engrave) the backs to hide the corner supports entirely.

Or maybe get rid of the tabs entirely and replace them with magnets. :thinking:
