The build looks reasonably straightforward. I suspect I wouldn't be able to use low-profile switches with this, but I'll fully admit I'm not well versed in keyboard assembly.

Thanks for this. I'm getting closer to what I'm looking for.

I bought an MD650L and found the switches to be unusably bad. I, too, wished for a low-profile Quefrency.

I'm comfortable designing and assembling PCBs but don't really have time to debug a brand-new design, so I've ordered a low-profile Lily58 kit. The Lily58 is most of what I want and has open source PCB, schematic and case. If it doesn't work for me, I'm expecting to modify it to something more like Quefrency.
