I designed this enclosure to help protect the electrical cables from young prying fingers. This enclosure also serves to direct the cooling fans between the Arduino and Ramps 1.4 boards. The enclosure features side and rear venting, a cutout for the USB cable and X axis motor. The mounting flanges make use existing holes that remained after mounting the Arduino and Ramps 1.4 boards. I placed only two mounting flanges so as to make the installation around the zip-tied cables much easier. I recommend raising the Z axis about 50 mm before installing the enclosure. This simply moves the motor out of the way during installation. I used Blue PLA that seemed to match the printed parts that came with the Geeetech I3 Pro B model. You will need to use some support material for the flanges to print properly. This enclosure does consume much of the build plate. I used a 2 mm skirt, and it barely fit on the bed. Overall size is approximately 4.25" x 3.25 x 7.5" (108 x 83 x 190) This part is pretty straight forward. I do recommend printing this part with support material to support the mounting flanges. Raise the X motor approximately 50mm before attempting to install the box. This ensures the motor does not bind the box against any of the cables during the installation process. Use a light fill 5-10%
