Hi Lynx Homebrew scene, I have been lurking for a while, but this is my first post, (so be gentle, if I'm breaking the rules ).
I recently fixed my Lynx I, which hasn't worked in 20 years. Then found myself buying some games and another lynx on ebay so that I could (finally) play with the comlynx - it used to be such a fraustration that I was the only kid I knew with an atari lynx... I guess I was just too cool for (my) school!
I have homebrewed up some replacement battery covers. They are available on shapeways at the following: Lynx II battery cover, Lynx I battery cover, I have also done a cart plastic & some Lynx 2 grips - though I think this works best in the elastoplastic - which is a maker only material, so not for sale.
They are still a little experimental, and I realise that they aren't cheap. 3D printing hasn't quite got to the consumer electronics level yet. But I don't know of any other products like this.... Comments much appreciated! I am fairly good at CAD so if there is something obviously missing from the lynx hardware portfolio let me know!
