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.
I made one of these. It seems to cool quite well (better than stock, confirmed with better prints) but I have a few issues which meant I have reverted to the original:
1: This hangs very close to the nozzle height, it will snag any print that has a whiff of warping to it.
2: Related to the above, and partly due to the length, it's hard to mount this hanging from one bolt. Any tilt on it is going to cause problems.
