Ultimaker E3Dv5 mount with Tilt z-probe

This is my version for an Ultimaker E3D mount. It features a retractable z-probe, which works together with a special part fixed to the construction platform chassis.

There is some Marlin code needed to make it work, I enclose it here.

Extra parts needed:

- 4x LM6UU linear bearings
- 2x M3x25 screws
- 1x M3x10 screw
- 3x M3 nuts
- 4x M3 washers
- 1x microswitch (6,60mm between holes) (may fit bigger ones, just drill where needed)
- 2x M2x15 screws for the microswitch
- 1x 3mmx32
