I couldn't find replacement cone/ diaphragm of my Philips TV speaker. So, I experimented with a 3D printed cone with TPU and it works! 

The speaker is just about 1.3 inch diameter and I think it rated about 10 ohms. I went through many designs out there and just couldn't find one that fits my needs. So, i design my own taking cues from many others.

The speakers sound a little towards mid tone now. Not an audio expert, so you might want to give it a try. 

F3d file included.
