Graber i3 - Y Axis Bearing Adaptor / Clamp

The Graber i3 3D printer is a Prusa i3 clone with a laser cut MDF frame (http://reprap.org/wiki/Graber_i3). Th kit I purchased, came with a solution to hold the printbed to the bearings using zipties.

Well, they work, but because of the heat of the printbed, the mdf structure bend down and colide agains the zipties holding the rails. Not ok, so I came up with a solution
