Canon 600D thin eyecup

Adapted the original (https://www.thingiverse.com/thing:1546457) to work with my 600D:
* cut 5mm shorter to fit above the display
* lower part cut in angle to match the body shape
* extra piece of plastic probably meant to press against the body in the upper left corner removed - did not work on my 600d anyway
* pins made shorter and thicker to match the corresponding shape on the camera

Assembly instructions:
* print cut.stl
* shape the large holes with a 5mm drill bit, if necessary
* glue all three parts together
