MicroCube with autobed leveling function-Titan Extruder

Thanks @Stargrove1 for this nice design. I have made lots of modifications as below:

Added nema 11 as Z axis with 8mm threaded rod.
Used a 220v 100W silicone heater as heated bed with a 2.5mm aluminum plate
Used LM8LUU for all axis (X, Y and Z)
Used aluminum rods for the bed and changed all design of the bed
Used a titan extruder and a designed a mount for it
Added autobed leveling function with an optical endstop and an 1.5 mm allen key

SOME NOTES:
*** X Axis Tensioner: It needs two M3 brass inserts:

*** Z_Probe: It needs to be glued on to the X carriage where there is a special place for it. You can use CA for gluing. Also you need a 86mm tall, 1.5mm allen key or similar 1.5mm width Stainless rod. When gluing be careful about the allen key should easily pass through its hole. It works with an optical endstop.
