This is a simple RAMPS 1.4 Mount for a Prusa i3 3D Printer which will stand the board off the frame to allow wires to be routed underneath. It has four wire anchor points (2 at bottom and top) which holds the wires in place. The 2 Piece Dual 40mm 12V Fan mount keeps the stepper drivers really cool, and is hinged which makes accessing the RAMPS Board a breeze.
