I started a project a while back to allow you to read and write to Amiga floppy disks from within Windows using an Arduino connected to the drive. The project is very successful (see http://amiga.robsmithdev.co.uk ) , is fully open source and includes full source code.
I adjusted the enclosure I remixed (by CMBS) this from to close off the back as access to this isn't needed.
You may wish to re-mix these further to help with assembly as I found the screw holes a little on the small size.
The models are also on TinkerCad at:
