One Apple enthusiast has managed to create a Hackintosh closely modeled on the Macintosh Plus, thanks to a considerable amount of 3D printing.

Some Hackintosh projects attempt to give users the chance to try out earlier iterations of Apple’s Mac operating system, without running on the original hardware. While users could seek out the older Macs in question, there’s no guarantee that they will be fully functional, or at least in some form of usable state.
It’s possible for enthusiasts to fix broken Apple hardware to have that experience, but sometimes efforts go down completely different routes. For example, one effort to modernize a vintage iMac G4 by adding M1 hardware from a Mac mini.
