They look very good but I suspect that normal PLA will not cope with the heat from the brakes as wheels can get quite hot.

Quite right. I only made one for testing, the plan was to mould, cast and paint some if I liked them. I decided I liked the look of the car without
them better in the end but it was a good challenge designing them to print in one piece.
To be honest even PETG reaches its glass point in/on a car very easily. I made
cup holders for my Range Rover at the time and
they loosened up from shrinking slightly in the heat.

As above, PLA is no good because of the heat. I'm using PETG which turns out fine on my Ender 3 S1
So far I've made a mount for the idle air control valve to go onto the plenum:
Draft in PLA
Final in PETG
Now I could do with one of those for mine. Is that a GBS plenum and how is it mounted to the plenum? Cant quite tell from the pictures?

One trick with PLA to make parts more resistant to heat if using 100% infil, is to boil the part in water for about 10 mins, the parts shrink about
5%, so just scale up to compensate. I've used this making electric motor mounts and works well, they are definitely stronger and last much better
when heated. I wonder if the same process would work on PETG to prevent the part changing dimensions later in use?

Yep GBS Plenum, mounted with bolts going through into the plenum. I got the idea from this blog
(richards-gbs-zero.blogspot.com)...same principle but 3d printed and
a hole to add a hose connector:

That looks ideal, does it work well? On mine I have just the throttle body cracked open but it sits at around 1300 to1500 rpm and it drives me mad.
Where do you tap the hose off to, is it on your intake line?
Could you post a couple of close up pictures too so I can see how you have mounted it please?

Yeah it's solid, and free air flowing...no issues. I've just updated my build diary so some extra pics of the overall setup there. but
here's some close up's of the part. It's got gasket sealant between it and the plenum, and a cardboard gasket between it and the valve.
The inlet is a threaded pipe connector that threads into the part, used thread locker there so it's not budging:
Hope that helps!

Interesting. I'm hoping to make some front upright dust caps (for a Sierra uprights they are now non-existent!) Shouldn't be too hot there
but will keep an eye on them given the above

Thanks for that. Yeah has given me some ideas for mine. I'll have a look at trying to design something for mine and see if I can get it 3d
printed, or even make me take the plunge and get one for the bits I want to do.

I can send over the .stl file if you do get a 3d printer. Or happy to print one out if not. Send me a u2u if you want either

You can save the files on thingiverse for others to use for free or even Cults 3D if you want to make some money from them. I save quite a few things
I design and it's amazing how many do download them.

Don't underestimate free software like Tinkercad, once you learn how to use it, it's actually quite powerful, plus because it is web based
it will run on some very basic machines like my little budget laptop which could not even run blender without freezing! I did try sketchup which I
liked, apart from I would then had to pay over £200 for the pro version just to save STL files, so went back to Tinkercad.
Tinkcad also has a lego & minecraft model generators, real time electronics designer/simulator and programming in code

I use Fusion 360, they still have a free tier that's fine for hobby use, main limitations are you can only have 10 'active' projects at
a time and some CNC cut path stuff is missing.
The active project thing isnt an issue either because you can activate and deactivate projects at will.

FWIW I tried many different CAD packages, I never got on with Blender/Freecad/Tinkercad, or OnShape, because I've been a bit spoilt with Fusion
360/NX/Solidworks/Catia in work but I did then find you can get a Maker license for Solidworks for 100 quid a year, which only requires that you
don't make more than 2000$ per year profit. I've been using that for 2 years now and apart from the usual gripes about Solidworks stability
(my machine is fully certified workstation with an i7 6 core and 32 gig of ram and a Quadra M4000 certified graphics card, but it still crashes at
times). Well worth it if you're just making your own bits and bobs, sending stuff off to workshops.
You can save all locally (I disabled the cloud saving nonsense) and get CAM etc for 3 axis no problem.

My point was if you don't have fancy cad software or even a powerful machine or don't fancy learning how to use it all, you can do some
quite advanced design work for 3D printing using some of the free online tools such as Tinkercad, which I have had great success with.

I learnt on Sketchup back when Google owned it. Still use it now & does exactly what I need it to. (it's web based now which I can't get
on with...still have the programme on my PC and I use that)
I did wonder about uploading...the things I've designed are very niche (see above) and I can't see a huge call for them. Maybe I should
rethink and upload them!

I know what your point was 😊. I was just adding the point that the free ones are often hard and long to learn and there's cheap
non-free commercial options. 👍
