Does anyone know what the correct original shape and dimensions are for the sun visor tips? I've been following the color debate, but I'd love to know length, inside and outside diameter, whether they were cylindrical or had a bulb or wider part on the end, etc. would also be helpful to know how hard or soft the original material was. Did they feel rigid, squishy, or somewhere in between (like, if you squished them would they break or give a little)? Did they have an inner lip that snapped onto the small indentation in the visor arm?
I've never seen any originals so hard to make a replacement without knowing what exactly to make. My teenage son is getting quite good at CAD programs and 3D printing and he's looking at whether these could be made and printed up (in black and/or white). He's already prototyped a couple other small parts for my GTC and if he can get them right we may see whom else is interested in examples.
