When I'm designing a pedal/module, I've always enjoyed working on the design layout in 3D so I can properly plan where parts go and make sure pots/buttons/leds/etc are in a place that make sense when they're all PCB-mounted. Make sure the lugs of a pot aren't bumping into another pot, or over the edge of the board, sort of thing.
So I was doing this here design and thinking holy shit, this is super dense. Is the control layout too dense even for me? Then had one of those lightbulb over head moments, prepped the model a little bit, slammed it in the printer and a couple hours later I had something tactile that I could touch to see if everything felt in nice places! Neat!
Probably not gonna do it very often. Only for the designs with the most dense/convoluted control layouts like this one.
I didn't print it on the box, in case you're wondering.
