Corner bracket for glass bed Anet A8

thingiverse

I was inspired by a design on http://www.thingiverse.com/thing:645203, but unfortunately it didn't fit my printer bed and glass size perfectly. I had tried using bulldog clips before, but these sometimes interfered with the auto bed leveling sensor. As you can 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 loading your design in the slicer, you will need to flip the design by 180 degrees to avoid overhangs. Making the arms 25mm long provided enough stiffness to keep the glass in position. I also made the bracket 1mm higher than the glass, which allows 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 on using the bed leveling screws to hold the clip in place, so you may need to replace the original screws with longer ones. You should only need two of these in opposite corners of the bed. If you want or need the other two corners, just use "mirror" in your slicer to produce a mirror copy of the design. I used Autodesk Fusion 360 for the design.
