With how many of these things break, I dont see a reason to reflect on how long a printed version will last. But at least it's not 200 dollars.

I didnt have the exactly correct bolt length, but once that gets in, proof testing time in the truck.

Pretty slick.
There are a number of low/no ash filaments now that can be run through a conventional 3d pringer for people who really want to do an investment casting of something because they dont like plastic. Wax filaments if you want to go jewelry grade.

Im fairly happy with "test run" right now just to get my door handle working again for a while.

#4-40 x 3/4" bolt w nylon lock nut (so it doesnt need to be torqued down to hold and risk cracking the seat).

Seems to work just fine. Fit in place in the truck, opens the door fine.

You could use a #6, but you would need to tap the bottom part of the seat.

Its installed and works just fine.

So I guess time will tell for how long. I printed the final unit out of solid PLA. I'm being positive minded here and hoping the increased flexibility and quality (versus the brittle and porous nature of pot metal) will give this guy a lifespan long enough to make it worth the trouble to install. Which frankly, now that I figured out the tricks on that, is trivial.

Have you tried printing this in ABS? That'll do a lot for durability.

I also suggest printing it in a different orientation. The way the layers are printed make the handle more vulnerable to shearing apart along the layer lines at the screw hole and what looks like a catch at the tip of your part.

The image is a little misleading on the layer question. Its got full length grain, for lack of a better term. It hasnt failed yet, but I dont use the passenger door all that much anyhow. Ill post if and when it does for sure though.

Still works. Been abusing it, but I dont have an ISO standard salt spray test or whatever for equivalent. Just texas summer and use.

I would file it under "this is an excellent option for anyone who isnt an originalist.

Anyhow, been busy arranging a 1082 to be it's buddy for a song and a whistle. That thing has no need for printed parts at all though.

My truck came with 3d printed handles, broke the third time I used it. Truck latches also needed lube so there was extra stress. I replaced them with aluminum ones and lubed latches.

I wouldn't use 3d printed parts for this situation. Considering potential high loads, it's not their ideal use case.
