Geeetech A10M extruder light bar for LED strip

This is a remix of the extuder light bar from Megasaturnv who remixed it from Hermiedug.

As i only got these RGB LED strips who got a cutable area every 10cm i had to rework some things to fit my needs.

- I extended the mount to the left and right to fit my 10cm RGB LED strip.

- I also added some clips to hold the RGB LED s
