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.
We have had no problem with ours. We used a MakerBot Replicator 2 and a 10% infill. As long as it is printed properly, it should be strong enough. If you are using different software or a different printer it might be a different story. Always be careful when testing it out, and always make sure to have the lid down or some sort of solid barrier between it and people while testing.
Could you post photos when you are done printing it out? We are very eager to see others make this project. Thanks!
