That looks like it might work. Its 9pm here so I'll print it tomorrow and see how it turns out, it might need to have the top part extended but I can handle that part, I'll post up how it turns out.

 

Oh btw is this just one side? I can't open it on my home computer.

 

Yeah just one side... you'll have to mirror it for the other. (I can send you an opposite if you need)

here is a quick update. GV_Brake_Duct_3inch_v02.3ds

I forgot to flare the bottom to suit the radius where the opening merges with the front lip. Its really hard to see in the photos so I have no idea if I got it right. It will be interesting to see how well it fits, if at all! lol

For some reason my cross sectional averaging didn't end up that smooth this time... if it fits I might redo that section.

 

I'll try and get in early tomorrow and get it printing. Updates/Pics tomorrow

 

Prototype for the R-Package complete. It's nice and light... will see if it fits tonight. It's great to be able to start with an idea, quickly model something up and then hit print and you have a complete useable part. There will be a big future for this sort of manufacturing.

 

Again, the 1000props button is missing... well done!

 

This is so damn cool. Excited to see it on the car!

 

In for a set for the gv lip. 3 inch duct

 

Printer was clogged up today, so test parts will be printed tomorrow morning or late tonight. I have to work around the paying customers so it may take a bit to get sets out but I know you and Nial want a set. I'll probably get enough made to pass around the local guys. I don't want to deal with shipping.

 

In for 2.5 sets. Lemme know how much $$ if you need it.

 

Will do, I posted in our local cr thread too. Will be sub $20 for sure. I have to work around the real paying customers so I can't give an ETA.

 

This is fantastic, props! Can you link to the file for this version as you did the GV?

 

My duct fits well... I have a custom radiator hanger that gets in the way a little so I'm going to reposition and turn the output so that the hose can fit with more clearance to the tyre at full lock.

In terms of the 'R package' version, do people want to trim the back off the lip itself or would you rather a solution that just fits to the stock lip? My one is already trimmed so the model I have currently will need modifying if people want to fit directly attach to stock.

I have found someone locally who has a GV lip, so I can test fit and adjust it here to suit. I'm currently printing that model so I should be able to test it over the weekend.

Lastly, I'm happy to print them here and ship individually or lots in a single box. Shipping will be fairly pricey though so it would be far cheaper for someone to print them in the USA and distribute. Alternatively you could take my model to a print place and pay to have it made.

 

Here is the current model: R_Package_Air_Duct_v01

Just note: this model is specific for my car which is trimmed back. I'm also going to be changing it a little so only download if you want to have a play. It's not ready for production. (this applies to the GV duct too)

I'll need around a week to test fit them and finalise, and then I'll release 2 variants of each (2.5 and 3") in both the trimmed R package, non trimmed R package and GV.

 

Thank you for all the info and file sharing, very generous.

When you say trim the lip, do you mean the portion that rolls underneath from the leading edge?

 

I typed out a message then figured a diagram would work a lot better. Excuse the bad drawing.



So I cut the red bits off as I have a custom splitter and radiator mount that gets in the way. If you look at my model it's printed on a diagonal to mate up to the diagonal cut. It needs to be flattened and shortened to work on the stock lip.

The benefit to cutting it back is that my 3D part is fixed closer to the bumper itself which means the mount point is stronger. The negative is that your hacking up a perfectly good lip to do it. I'll make a version that mounts over the stock exit, just need to find someone who hasn't cut up their bumper. I might have kept the offcuts actually.

 

Nice design. Well done sir.

 

What material are you guys printing these ducts in? ABS?

 

I'm printing in pla plastic just because I have lots and it prints well. Abs might be a better choice as it is stronger, more flexible and has a higher melting point. The negatives to abs is that it is more sensitive to UV damage and is a bit tricker to print well.

Pla for this purpose should be fine. The parts are very strong given their shape and they wont see any heat.

I haven't had a chance to do any more on these yet. I spent all weekend painting a car... I'm glad they are small! I have printed the GV lip duct but I am yet to test it on a car.

 

Pretty stoked to see a test. I have like 5 or 6 local guys wanting some.
