This is a replacement for the hood latch level mount on the 1995-1999 chevy vehicles. Both of the ones on my 1999 and 1996 Tahoe were broken at the bolt mount, printing these are pretty easy.
Remove physical handle from old latch assembly, along with spring without damaging it, and place onto newly printed mount. Secure the spring with the "chevy stopper" part with a few drops of super glue. Then place the "glue square" in through the new mount (wide end sits on top of the mount face) and super glue that in. Then put into slot and replace bolt. Do not over tighten.
30% is plenty strong for this application, however I see no harm in increasing fill if necessary, will just use more material.
