Lamp holder for Marsaqua 165W LED

Instead of hanging the Marsaqua 165W LED Lamp over my fish tank i wanted to sit it on the glass. So i constructed this Lamp holder. You have to print it 4 times. It is designed fro a tank width of 500 mm with 4 mm glass thickness.

I have printed it from ABS with 30% infill. In addition you need 4 screws that are a few mm longer than the originals. I think the should have a M4 thread.

I have provided the FreeCAD-File. You should be able to modify the model if you need a different height or
