Some time a go I wanted to meaningfully upgrade my home audio gear - I decided to buy a Digital to analog converter, because the signal that is coming out of tv or phone headphone jack is of a questionable quality... After some research I found out that like with every audio gear the price does not goes linearly with quality - cheaper DAC's were shitty and the better ones back then costed a small fortune for me (as I was still a student... 😄). And of course I couldn't be more disconcerted by audio industry snake oil advertisement, so at the end I bought a pre-assembled PCB from Aliexpress with PCM1794 DAC from Burr-Brown. It only needed a two external transformers to work, so nothing to worry about! I assembled it on a foamed PVC board and it was sitting like this in my entertainment unit for few years, but thanks to my recently purchased 3D printer I finally had a chance to give it a proper enclosure! Before printing I had to learn how to use Fusion 360 and design the enclosure It was a fun but I am not a big fun of autodesk product, I think that they could be more intuitive. I always wonder how people can use eagle for PCB design if there is Altium or KiCAD.
For the printing material I have used a PTE, because of it thermal stability. While printing I had some first layer adhesion problems (bed temperature turned out to be to low for such a large print), but the whole print turned out to be very good. It took more than 20h to print it!
