All …OK well mostly with 3D printed parts. The press is used to heat up metal, such as nut inserts, to push/melt into a plastic fitting. Great for say a plastic box that needs it. Me…unless I am making a bunch of these, I just will do it by hand. Still a nice build and idea. And ALOT cheaper than anything you can buy.
