A simple side stand for my Modi 3 DAC that allowed me to place it on the same stand as my record player where there was limited space.

I printed mine with .1 layer height and it was a perfectly snug fit. You want it this way so your cables don't just pull the DAC out of the stand. I would have liked this to be a bit heavier but I have not has any issues with mine falling over when messing with wires.
