I've had these done for a while now, been holding back releasing them because I had meant to get some GPM numbers, but I never seem to have the time. So I figure I'd rather release the files than continue to sit on them.
I like gentle curves, and I didn't want to modify the top plate as I recall - wanted swappable bases. I made these 6 months ago or so and don't recall the exact reasoning behind everything.
