I loved the anti-sound enclosure. It was exactly what I was planning to do. The only thing that didn't appeal to me was the handle - I wanted to put something central vertically, maybe use it to help hold the two halves together (in the final version of the enclosure this wasn't remotely needed). And I had a different magnet size on hand.
So this remix:
I was printing with silk PLA so my tolerances weren't great. One magnet is friction fit and still solid - the other I had to hot glue in place. YMMV.
