Mosfet Mount for Ramps - for heatbed switching

This is my solution to mounting a seperate Mosfet High current relay for 3D printer heated bed:
Printable mount to hold a Mosfet relay (from ebay ) for use with Ramps or other 3d printer control boards.The Mosfet relay seperates the high current switching action when using a heated bed,away from your Ramps or other control board.only linked by a 2 wire control to the Ramps board,
This Mount has 4 x 3mm Dia holes for mounting,and 2 x pillars to attach a perspex strip to cover the heated bed ter
