Prusa i3 MK2s Z Axis Strain Relief

If you can't seem to get your Z Axis cables and the 3mm nylon stiffener to stay put in the Rambo Cover opening then this will do the trick. Its designed to use one of the existing holes in the frame above the Rambo Cover, and one M3x40 allen head bolt from the Spare Parts bag to keep your Z Axis cables from falling over and possibly fraying on the Rambo Cover.
