Endoscope mount

I have this(https://www.thingiverse.com/thing:5332386) hot end cooling system and i wanted to add an endoscope to it so I designed this piece that screws onto the front fan

i used a hand drill to make the holes big enough for the screws that came with the noctua fans i am using. i also had to use a razor blade to clear the elephants foot inside the hole for the endoscope.

i used a 5.5 mm endoscope this model will only work for a 5.5mm endoscope

i used 1 3/16th hand drill
