My old tail light nuts and rear hatch trim clips literally crumbled in my hands as I removed them. For a grand total of $9, my local public library printed me 10 tail light nuts, 6 trim retainer clips, and 4 new plastic trim screws. They are made of ABS filament so should be able to withstand summer heat.

I can't take credit for the 3D models, I got them from Thingiverse:

That is fantastic, never heard of a library doing that

 

Libraries do that???...

 

Quick. . .ask them if they'll make grille inserts for 82-84 Z's

 

My local library system has two really nice 3D printers. They print the files at the central branch, then they deliver them the next day to my local satellite branch. All I pay is the cost of materials.

 

I actually looked already, mine are shattered too, but I could not find a cad file that somebody already created. I was thinking of designing one myself.

EDIT - I actually just found a cad file!

Is the hole for the Sport bumpers the same shape as Z28?

 

You'd be surprised what libraries are up to these days. Tool loans, 3d printing, e-books, tax help, health insurance help, all kinds of stuff. It's not just a room of books these days.

 

You people do know you can buy a bag of these already made right?

Real injection molded parts with foam rubber seals.

 

A lot libraries have really cool services. We have a library that has 3D printers as well that you can use. They also have huge movie DVD/Bluray library thats all free with library card.

 

Yeah, for 4x as much. The factory ones don't have foam seals, so these don't need them either.

 

I just took the taillights out of a Buick Grand National and it had wingnuts that looked very similar to the ones in my 91/92 Firebirds and the GN ones had a foam rubber seal in a slight recessed area of the base of the wingnut. I haven't yet removed the taillights from my Firebird so I have no idea if they have a foam rubber seal or not.

I just figured how many different types of taillight wingnuts did GM use to hold taillights into 80s/90s GM cars. I got a bag of 10 for around $15.00

How easy did your 3D printed wingnuts self thread onto the mounting studs of the taillight?

 

Easily enough I didn't have to force them, but with enough resistance I'm confident they'll stay in place properly.

 

Mine had some sort of foam seal but it was pretty well deteriorated so I put a little 3M strip caulk under me

 

Was the librarian hot too? But seriously, ida never thought your local library would offer anything like this.

 

They are different, I believe, however I just found you can buy a new pair on amazon for $45. What a time to be alive!
