Veery nice effort
A nice guide.
Only point I had thoughts about was washing plastic parts in a dishwasher. Won't it warp the plastic? Probably varies between different types of plastic, it worked with yours, so
When I have time to prioritize it I will think of a way to make a nice little slit in my A1200 for an SD card instead of something warm, less reliable, and noisier with clunky mechanical parts
Perhaps also a built in DF1 and a TFT ...
