This is a simple extension bracket for the Andonstar AD407 microscope. With it you can put larger PCBs underneath it. I recommend you also upgrade the table.

Should be an easy print, no support needed. I used 20% infill.

For mounting you need 2x M4+ring+nut. You could use M5's to secure the microscope but with my print the fit was snug enough and not needed.

STL and Fusion360 files attached. Enjoy!
