This question has a bit of an arts & crafts / DIY flavour, but looking at those Stack Exchanges made me feel it fits better here. I have no background in any of these things, so apologies for my ignorance, including any poor etiquette! I'm happy to improve the question if people provide feedback - or, I suppose, to remove it - but am not sure it'll be better-received elsewhere.
I'm interested in making a globe, around a metre diameter, that can be easily assembled, disassembled and carried around in a compact form. I was thinking of using 20 hexagonal and 12 pentagonal pieces, like a football - I'd prefer them to be curved, and ideally 3d printed so I can easily add colours and/or texture on the outside. But I'm not sure how best to join them together (triangular joints? hinges? struts? elastic bands? I have no idea), or what materials and thicknesses to use. My main constraints, roughly in order, are budget, weight / compactness, durability, ease / speed of (dis)assembly, and ease of manufacture.
What are some sensible approaches?
Bonus points: it would be nice if
- the structural components aren't too visible from the outside
- I could assemble 3-7 pieces and have that be stable by itself - so I'd prefer not to use a ball in the middle with long rods coming out, but if that's by far the cheapest solution then so be it
- (extra bonus) I could attach and remove small objects using paired magnets or something similar
