8mm Film Scanner V2

finally all components arrived and I could assemble the HAT.

I also decided to go with an SSD drive for optimum performance. 

if you want to test the new core unit, I've put the stl files on my gdrive:

Important note:

The mount plate V2 is not compatible with the version 1 of the scanner. I've added a compatible version.

I've used PETG for the mount plate and PLA for the rest - all printed with a 0.4mm nozzle.

the front case needed complete redesign to make space for a larger 5 inch HDMI display.

the buttons are now below the display. The cover is printed in one piece, including the buttons. Only a color change was done after the first three layers.

In order to provide cooling to the Raspberry Pi 4, the new design has space for a cpu cooling fan. The GPIO assignment is new - so it is not compatible with the software of the original scanner.

It also includes now a switch to toggle between S8 and R8.
