Hello!, and thanks to 360alaska for sharing the files!
I gave the Macintosh Portable foot STL file to a local 3D printing company, and after a few modifications they were able to print it using a flexible TPU filament. the quality is not perfect, but it fits nicely in the portable.
They also told me that they have the equipment to print object with a much higher resolution using a special flexile resin. The only problem is that such material is crazy expensive (about 400€ for a bottle) and since it has a shelf life, they can't get a bottle for printing just a couple of small parts.
The good news is that they can model and print other parts (like the quadra 700 foot) using the same material.
Using the same machine (and hard resin) they were also able to reproduce the gears used in the floppy drives.
Essentially, if you gave them a physical object, they can easily model and create an accurate 3d printed replica.
