Print in black PETG for temp resistance. Print at least two for the most control of the cables location.
The two small bump-outs are slightly different diameters. This is because my 12v and USB cables are different diameters.
The bump-outs are 90 degrees apart because they are intended to line up with the diffraction mask I have designed. I would highly recommend printing the aperture mask as well.
The author marked this model as their own original creation.
