Assembly Tips for Installing Threaded Inserts into Plastic

A look at the springs installed under the printing surface. I apologize, I forgot to take a picture of the materials for this step beforehand.

The springs can be difficult to wrestle into place. I found it easiest to put one on (screw through spring into threaded insert), but only enough that the screw catches. The spring provides enough leeway that the other springs can be held in place while a screw is threaded through. If I get a chance, I'll post details/pictures of my technique Pkiddy 15:12, 15 November 2006 (EST)
