GREAT!

Please don't use links like this. Make sure to use a link to an image extension, so the image will be embedded. Thanks.

The actuators are here

The relation between stroke and length is good, only the guidance in full extracted position should be better.

[efferman]

The rims are here .Sorry for the white out

Racing wheel medium

The offset seems nearly to large

Racing wheel small. Are there no low tires?

Offset like on the standard rim

 Tire from 42039 24 hours racing car

 Tire from 42054 Class

 Tire from 42000 F1. I like this match!

 Tire from 8110 Unimog

 Tire from 9398 rock crawler

Thanks for great wheel.

And one complain. Worm gear counterpart double is to stiff.

[efferman]

in which way it is to stiff?

[syclone]

I am thinking of placing an order from Shapeways in near future for a project, and one of the pieces is the 20z diff. I saw that you had it 3d printed in the video demostration , do you know how strong it is ? I plan it to rotate at high speeds and I'm concerned how it will hold up the stress.  

[efferman]

Never had it at highspeed or high torque, so i have no idea

[seberget]

What do you guys do to clean up and/or loosen up the pin holes on these parts? I received the Leaf Spring 11L 4 piece set yesterday, and the wholes on some of the springs are a bit tight. I'm also thinking of ordering the Torsen Diff 36 Z and would like to know what you have used to polish/clean it.

Keep up the good work @efferman!

[efferman]

For circular holes i use a 4,8mm drill or something similar

[AFOLegofan66]

for complex 3d printed shapes I use a small stainless steel brush. It looks like a tooth brush but very handy. Of course drills are great for any holes and wet and dry sand paper for flat surfaces.

[nicjasno]

Would it be possible to adapt this into a 3d printed model? It's a rotational pneumatic valve. Needs some work and simplification.

I have designed this in a pre-3d printing era, so it needs to be reengineered to use as little material as possible and be smaller.

[efferman]

Where are the seals?

[nicjasno]

It's just an idea for a rotating pneumatic valve. It needs work. But i guess one could find off the shelf o-ring seals and design a groove into the rotor or housing where they'd sit and seal on each side of the rotor. But i don't know how to seal the circumference.

Hi

I am looking for wheel covers for the Mercedes AMG GTR in black for the 56mm wheels. Is this something you can do?

On shapeways most of the designs are only available in white it seems. Has that changed recently? I do remember that before you could choose which colour you wanted to use.

I am going to take a wild guess, and say that is your next project?

You may never guess again

I thought so, and I spotted @Charbel's next project. 

Ok, never again, but, others like efferman would figure that one out in a minute.

[efferman]

Jeroen, this design is probably not solid to make as rim, and as a wheelcover the standard rim will fully visible.

For the colour, the painting, except for black is a gamble on shapeways, so self painting gives better success.

Thx for the quick reply.
I want to use black rims behind this cover, so that is not too big an issue, but fragility is...

I do not fully understand your comment about the colour. If I choose a white design I do not get any options in the pull-down menu of the colour, except for white. For me shapeways does not offer a paint option.

[efferman]

The seller has the option to make different colours available. Maybe polishing, which is necessary for colouring, is to stressfull for the design and allows no colour option. So the seller makes only white available.

Have you checked sevenstuds designs? He has some wheel covers would possibly fit.
