Improved L for andreasL's alternative Z for SmartRapCore

An improved model of the left corner holding the motor for AndreasL's alternative Z axis. This piece allows for more teeth of the belt to contact the pulley. In addition, the motor is mounted with all 4 corners.

This model requires 2 extra 608ZZ bearings. You might want to use 2 d8 stubs or pieces of 8mm wired rod to mount the bearings.
Also, the timing belt should be a few cm longer.

Edit 29-2-16: A modified bed carrier has been added.
The improved corner piece will reduce the bed mov
