Ender 3 Logitech C270 Bed Mount

Modified the Logitech C270 bed mount for the CR-10 by DigChaos to fit an Ender 3 bed.

Changes:
- Lengthened the horizontal part attached to the bed. This moved the camera out of the way so the hot end / fan enclosure did not hit the camera when auto homing.
- Shortened the diagonal / vertical part to move the camera to a lower point a view. This allowed easier viewing of the hot end for shorter prints.
