Here is my latest Mini-z body: Porsche 917 K from 1970.

Real car:

The Porsche 917 K #20 was driven by Steve Mc Queen in the movie "Le Mans" from 1970, watch this (http://www.youtube.com/watch?v=rHaRfKOwdL4)

Mini-z version:

Wheelbase 98 or 102 mm
Offset +2F/+3.5R
Weight: 22 grams without paint

The body is super low and wide. It is comparable to a LM body only with 98mm wheelbase (102mm will pass due to the shape of the rear fender).

I made special wheels for the 917.
They can use normal tires and have fake tire walls to simulate classic wheels. The rear wheels are 14mm wide and F1 tires can be used on them.

Beyond outstanding. You will have a very difficult time topping that one. You are approaching fine art.

Without a doubt the best you've done so far :) not demeriting the others but the 917 is the sweetest. Great Job!

I've just ordered one of these, can't wait to receive it.

I've tracked down the decals for it and now trying to find the paints for the Gulf colour scheme.

Fovea, which brand of paints did you use for the blue and orange? I know Zero Paints via HiroBoy do them but they do not ship overseas.

Thank you all ! Yes this is my favorite so far :)

Fovea, which brand of paints did you use for the blue and orange? I know Zero Paints via HiroBoy do them but they do not ship overseas.

Orange: TS-31 bright orange Tamiya
Gulf blue: no match with Tamiya TS. As I don't have an airbrush it had to be a spray can. I found this, even if it is for Lexan it works well:
http://www.teamhobby-modelisme.fr/boutique/produit/487-bleu-clair-blue-gulf
It does not react with Tamiya TS paints.

Order for paint process:

3 coats Motip filler primer with light sanding between coats

1 coat Tamiya fine surface primer (to have a white base)

2 coats of blue

masking then 2 coats TS-31 bright orange

I made the black borders with electric tape strips of 1mm (the clear coats will seal them).

masking then 2 coats of TS-29 semi gloss black (windows)

2 coats of Tamiya TS-13 clear to seal the paint + black strips and prepare for decals.

Decals (very easy to work with if the ones you mention are from 3MD Model, I used the photo edged wiper included with the decals)

Then several coats of Tamiya TS-13 clear. Small bubbles appeared on the decals with the first coat but pressing/wiping them and the following coats arranged this. Now its feels like Kyosho glosscoat (with the decals merged inside the clear coat).

Good luck!

Thanks for the tips Alain.

Just need to wait for the body to arrive then my paint project will start.

How about a photo of the body as it comes out of the printer. I assume that it isn't like it is pictured in photo number 8 next to the 962.

The picture next to the 962 was with 3 coats of Motip filler primer.

This is straight from Shapeways with the accessories still attached to the body. Everything snap fits, only the motor cover can not be used with the standard shock absorber but it does not look bad.
The rear chassis section with the spare tire looks fragile but it is not. It can flex until it touches the motor pod with no harm. Of course you can choose not to use it to save weight.

Excellent. Although. To be period correct the tires should be Gold lettered Firestones with a small gold stripe running around the circumfrence of the tire just inside the tire shoulder.

I imagine that the wheels are an option and that the wingfoot can be sanded off? The front wheel diameter is?
If so how much do the wheels add to the price?

You are right, I should read Firestone. Anyway I need to edit the wheels file because I got some rejections from Shapeways due to the embossed letters being too fine. The wheels are in the mini-z parts section in my shop, not available until I edit them.
Wheel is 20mm at the tire sole, 21.5 with the tire shoulder.
The simulated classic rim is 16mm.
What is great with the tire shoulders both sides is the tires will hold better. I may also add 0.5 mm offset front. Rear is perfect.
The price for the wheels was around $15.

If memory serves correctly the real car ran a 13'X10' front wheel and a 15'X15" rear wheel. Using F-1's for rears would scale out close to correct or a new LM rear tire with an LM front tire. The current Sauber wheel is very close except for spoke count. The originals had only 5 spokes.

I realize that I put 13' all around. I will keep this in mind when I edit the wheel parts, thank you.

This body is close to 1/24. In full size, the 917 is quite a small car.
Now in 1/24 it is comparable in size with the 1/28 962.

I choosed this over true 1/28 because it would have been narrow with 86mm wheelbase juste like the kyosho 906. Not really raceable, and I didn't want that.

The F1 tires are slightly too big (about 2mm in ). To keep a lower stance, I used a spacer between the motor pod and the H plate.

I cannot find fault with it in any way. I will have one.

Now. If you could just tweak the Cadillac CTS to use +1 fronts and +2 rears everything wil be right with the world.

Wow, I went on vacation for a bit and came back to this, Alain? :eek: It looks outstanding, the raw Shapeways print is looking very professional.

:p i would certainly +1 for this as well. grille textures at the front, 'detailed' headlights similar to the 916 would be awesome as well.

the printed parts alone looks awesome for this kit!

how does the back panel attach to the body? screw posts or glue? if glue, what type of glue works best with this material?

There are 2 rails where you slide it in place. You can use double sided tape to secure it so it is not permanent. To make it permanent CA glue (Superglue) is the best because it will infiltrate the porous material.

How long does it take Shapeways to complete the 3D print?

It has been a 3-4 days since the status of my order went into "Production" but it's still sitting on that.

About 1 week from production status to shipping.

A couple of months ago I placed an order for the body with Shapeways and they said it would be begin shortly. The next email said it was in production. After a couple of weeks, the next email said they couldn't do it and refunded my payment. Anybody know whats going on?
Thanks, Bob

Hi Bob,
I am really sorry. While the 3D cad of the 917 hosted by Shapeways is still the one that was used to print my prototype (the Gulf blue 917), it does not fit their design rules anymore.
From time to time Shapeways changes the design rules, reducing tolerances for thin parts. I think the reason is that because of the huge success they have, they reject models that are too difficult to clean out.
I need to make the wipers and some other structures thicker in order to make the 917 printable again, currently Shapeways marked the model "rejected".

Bonjour, Alain
Thanks for the information and explanation, it makes sense.
By the way, I found out that Fujimi makes a 1/24 Porsche 917 in several versions and I ordered some of them. I got them through Far East Hobby Search for reasonable prices and quick shipping. I thought you might want to see them yourself. I'll start a thread on building the first soon.
