Thank you for sharing this! I just got my first printer a week ago and was very happy to find this model. I've been wanting something along these lines forever on the master bus of my Mackie 1402-VLZ3 - fits great! I also printed one to test on the channels - also worked great. This mixer uses the 24mm faders.
It does cover more of the master faders than I was imagining (that is, entirely covers them) but you can still see the indicator mark to the side. I'll likely print some up in white to match the rest of the mixer when I have some white filament handy.
Printed in 0.2 resolution, 100% infill as shown in description
