Print the component stl's you need.
The LCD cables fit through the slot in the bottom of the box.
There is the: box, top, slides X2, and Legs. The legs can be used single or print a pair for four legs. My use for the legs was to mount the box on the side of my printer and using one set of two legs supporting the other portion of the box. This should be evident in the included photos now you know how I attach the box. ;-)
These parts are for a lengthened version of the YARB. This version has wings to allow the use of a LCD monitor card attached to a RAMPS board. The cover for the box has two small extensions which print separately and are easily trimmed with a knife and glued to the cover. These small extensions cover the wing slots for the LCD. I've also included legs which lift up the box approximately 25.4mm. My YARB is attached to the side of my printer with a slide attachment and one set of legs. You possibly could print two pairs of legs for the box. I simply 'Hot Glued' the legs to the bottom of the box. Orientation, position and placement are not critical.
I hope this works for you...
