MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Unfortunately I can't say what will work for your machine however I try and make my designs "safe ' to print on most machines. You can try printing the loose version uniformly scaled down by 20%... that may cut an hour out of the print time. .. but the risk is that it is fused so will never spin and you're back to doing a 4hr print to get a good result. It's also worth mentioning that the size adds weight and helps it spin.
I hope this helps
