Pen adaptor fanduct (LPA V5.0) for Tevo tarantula

Hi, this is my LPA V5.0 modification of the original model by Laurent for the tevo tarantula.
This modification allows the use of a pen to convert the tarantula 3D printer to draw 2D prints. The setup is very simple and quick. Just insert the pen and secure it with the screws.
To convert back to 3D just remove the pen. No extra actions on the hardware are required.
To draw stuff you need to use Cura software and create a different profile with some specific settings.
