Print the parts with high infill for good stiffness. I used 50% infill and printed the mount with black PETG filament. You will need: 4x M4 x 12 mm hex screw 4x M4 washer DIN 125 6x M4 washer DIN 9012 (12mm diameter) 4x M4 locking washer 4x M4 threaded brass insert 2x M3 x 8 mm hex screw 2x M3 washer DIN 125 Insert the threaded brass inserts with an soldering iron. Then assemble the parts as shown in the fotos.
