Can someone help me combine models to print?

Hi everyone,

I'm working in a school right now and the computers we have just don't have the power to combine models properly, they just break down when we try.

Would anyone be able to do this for me?

The link is below, essentially what we need is the front "face" and the back sections made into 2 parts rather than 4 so we can 3D print and we're just unable to do it with our out of date hardware.

If anyone can help I'd be so grateful! :)

Joe

I've found that with my slicer program (XYZware, but I don't recommend it overall), I can arrange the STL files, pre slice, to overlap just slightly and the slicer will treat them as 1 object.

Looking at the site, I don't see an easy way to view the STL files, so I really can't comment, although the description states it's already in 2 files.
