When you lose the cover for your Amiga 1200’s expansion port, or even worse damage the front door to your Commodore 1702 monitor’s control panel, what do you do? Similar to the Nintendo Game Boy’s battery cover, replacing these individual parts is a difficult task requiring you to rely on eBay users to lists spares, as and when they find them. That’s all about to change though as a 3D printing enthusiast has set up shop selling those easily lost parts from retro computers and consoles.
