Short Reset Knob for RepRapDiscount Full Graphic Smart Controller Case

This knobe was protruding a bit too much in my opinion, as it's a kinda dangerous button, so I shortened it by 2mm so it's nicely aligned with the front panel of the case.

The shorter knob is still easily clickable with the finger, but no more risk to do it unintentionally!

I also designed a vertical holder, you migh want to check it out [here](https://www.thingiverse.com/thing:2932549)!
