(Btw, my Ultimaker 2 prints 22x22x24 or something so I can do quite large parts. Unfortunately just below a complete lunchbox MSTE bay ... )
I've done a Mega STE VME-backplate as well with mounting holes for the Lightning-USB ports. It's in that thread.
I don't spend too much time on making things pretty, so a lot of things are just functional (like SCSI2SD holder for a Mega STE lunchbox original hard disk version) - those I never upload anywhere.
Great initiative. The one thing I've been looking for myself is Atari frontplates for Epson 300/340/380 disk drives. I replace a lot of faulty Atari diskdrives with original Epson/HP versions, but I've now run out of original frontplates ...
