Very neat indeed.

So what sort of music do you make ?
Lots of mikes, guitars etc in your workshop :-)

Does the hood make a significant difference ?

I've actually found that abs warps a lot less (well no warpage at all so far) by simply running the printbed at 100c and not 110.
I actually set the temp to 110 - but the 3mm aluminium top plate only gets to 100. And nothing's warped since. I did do one print at 120 (so 110 for actual print surface) and that warped a bit. Exact same print at 100 - no warp.
