Corner bracket for glass bed Anet A8 by David_en8

I was inspired by design http://www.thingiverse.com/thing:645203 but inevitable it didn't fit my printer bed and glass size!
I had tried using bulldog clips but these interfered with the auto bed leveling sensor some times.
As you will see from the drawing I measured the distance from the edge of the heated bed to the glass edge when the glass is centered. In my case it was 12mm from the front/back edges and 4mm from the side.
When you load your design in the slicer you will need to flip the design by 180 degrees which will avoid the overhangs.
Making the arms 25mm long provided enough stiffness to keep the glass in position.
I have also made the bracket 1mm higher than the glass, this is to allow for the clips to hold the glass down as the flat edge that holds the glass in place is only 3 mm high.
The design relies upon using the bed leveling screws to hold the clip in place, you may therefore need to replace the original screws with a longer one. You should only need two of these in opposite corners of the bed. If you want or need the other two corners then just use "mirror" in your slicer to produce the mirror copy of the design
I used Autodesk Fusion 360 for the design.
