Needed something to guide the cable from the RAMPS board to the extruder. Designed a simple holder that can be attached to the backside of the upper left Z-axis holder. You might have to replace your (2) M3 bolts by others that are 5mm longer. Should have made this a long time ago.The SCAD file contains to some work of others to create the space for the M3 nuts. Just print it as you normally would. Nothing exciting from a printing point of view. (printed at 0.2mm layer, 3 perimeters, 50mm/s, 205 degrees C PLA).
