My turntables are in travel cases, and the mixer has been suspended between them, with a digital audio converter slipped underneath. I wanted a solid stand for the mixer that would allow the DAC to still fit underneath, and provide a better place for the laptop.
The laptop stand itself has already undergone a few iterations, and will certainly change again, as I have already discovered a few minor issues, but all in all it is working great. The current version uses a base and hinge modified from the iPad stand design by @polarbrainfreeze.
