[TriEmbed] Large Format Laser Cutting Needed

[Adam Haile]

Responding to the one with everyone this time :P
Ah, cool, I didn't know Pololu did laser cutting... RMS is close, but I'd
still have to break it up since I basically need 40"
I'll get a quote from Pololu...
Thanks :)

Just noticed... seems they don't have cardstock or anything as a material
option... I could use something thicker but would have to redesign my
baffles...
