Quoted from Zitt:
I've done some more work on the speaker wraps; basically divided them up into ~3 inch sections so they could be printed easier on the Makerbot build platforms. I wasn't sure that 5.9" tall would print on the Makerbot Techshop has. Since I divided the one wrap into two sections; I put little "snap" dowels into the pieces so they'd go together and could be glued in place.
I'm thinking the best material would be ABS. The wrap in grey and the vanes in black. If only techshop had a makerbot 2X... then the wrap could be printed in dual colors (IE vents in charcoal and wrap in grey)
I'm kinda hoping someone with 3D printer at home will step up to own the print of these wraps. I feel like these buggers are gonna take several overnights to print... lots of trips to Techshop which could be used assembling other aspects of the machine.

Not sure if you're printed this yet, but I'd suggest PLA for a part that big on the Makerbot.
Even with a heated platform, and anti-curling tricks like hairspray, ABS tends to contract upon itself at the base on larger prints.
