Thanks, I got it as a factory second as it has a huge crack in the veneer. Still turned out pretty decent and it actually sounds pretty good. I wanted to take some better photos but was too lazy so far...

How do you transfer the design to the enclosure? I am using toner transfer with an old (but professional) laminator that can go up to 160°C, that works very well for flat sheets of metal.

I guess a hot iron could work for an enclosure, or maybe an old heat press (for transferring t-shirt designs)?

Otherwise, you could of course also stencil the resist on with spray paint, or maybe try a vinyl cut?
