Holder for Nevermore V6 filtration system. I use 3xM3 screws that I found around to  screw it to the holder. There are two additional teeth from the bottom that supports filter carriage.

Attention! Holes does not fit perfectly as it deepens of Qidi assembly, you may need to drill hole off. Please find attached .step file, feel free to make changes.
