success! got the switches from syntaur last week and the buttons + bezels from shapeways today.
the bezels fit on the switches as do the buttons, the bezels don't fully 'click' onto the switches but the buttons do, and hold it all together fine it feels as sturdy as the real buttons.
the only issue for me was the plastic print i ordered is kinda fuzzy and almost spongy, but it's totally fine. if i was to do it over again i would order the hardest, glossiest version.
thanks so much for making these! i am sequencing away.
