Each of the sketches was exported as a DXF file, then combined in LaserCut to get the final file. When I did the initial cut, I didn't anticipate how the small size of the stars would cause the laser not to cut through well enough on the default settings. Since the clock face came out easily enough by itself, I didn't think that it would be a problem to remove the stars, but when I tried to push the stars out of the acrylic, I actually ended up cracking off a piece of the clock that as meant to stay! The circle in the center came out fine, however, so I ended up using it to test the fit of the clock kit.
