This is a 1:1 scale replacement for the bottom plate of the Apple Disk II drive. It's not 100% as where it slims down on the metal plate, there are screw holes so close to the edge that I felt it would be an issue once printed in PLA. I didn't have any issues in fitment with original metal cases or PLA printed cases.

I started by separating the parts in option8's design. Once I had the bottom plate isolated, I removed the feet. Then I scaled it to 1:1 size. I replaced the front lip with one I was given by Javier A. Rivera. I then added the screw holes and spacers.
