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.
Yeah, I'm going to standardize the size for those. They're easy to remove provided the print came out as it was supposed to (no warps near holes, etc). I personally push them out with a screwdriver.
You can also take a look at one of the first makes, where a user has already used bolts and nuts instead of pins - It's just a matter of asking him or her what size ;)
