if purists the short u joint would accept when it would be red?

Your question is hard to understand. Did you intend to ask if purists would be ok with the part if it were made in red? No! But it sure would be pretty!

[efferman]

a long time ago the lego u joints are being red and with a shape like this

[OzShan]

Making the valve body a through hole is good. It could then easily be drilled/reamed to provide a better surface. Stackable is great, but could the connector be thin so you could attach a thin lift arm and keep the stack tight?

Great work again

[dhc6twinotter]

if purists the short u joint would accept when it would be red?

I think red would be fine. The older u-joints were red, as you mentioned.

[efferman]

because the valve body is 11mm thick, there is a minimum of a half liftarm to the next part. so it is enuogh space.

btw, yellow and green are now available for printing

[JaapTechnic]

A long time ago i have also redesigned the valve which was originally designed by Barman.

Your version is almost the same but mine uses pneumatic tube for the seal, not sure if that will work...

Because i would like to keep the lego design in it, I came up with this:

I have never tried to print it, the planning was to make it with broken mini pumps.

[efferman]

i had thought about the same design. is there anything wich prevent the piston for pulling out?

a first bunch of parts are arrived

[JaapTechnic]

Not yet, in this design the piston can pulled out.

But maybe it's possible to reuse the caps which are used on the small pumps to prevent the piston to be pulled out.

The universal joint is very strong

Much better than the lego version which breaks really fast

[jorgeopesi]

if purists the short u joint would accept when it would be red?

I don´t accept it even in red but I admit that you do a good job. We will see if Lego copy any interesting part .

[Rockbrick]

a long time ago the lego u joints are being red and with a shape like this

[Zerobricks]

I have 3 of those and 1 broke (dont ask how i managed to break it) They are really tough, the plastic is much harder IMO.

[z3_2drive]

I broke about 3 But recently I bought 9 from Germany as they are the only ones that can survive 4 buggy motors in constant stop/go motion. These u-joints look similar in strength, and the sliding function is a huge plus Red would be somewhat nostalgic and fit with the range of Technic pieces, unlike white.

[camaudio]

universal looks nice and strong, will be getting some!

Hello efferman,

I really like these custom part's. But just a quick question, are the 62X20 rims packed by 4 or is it just a mistake in the photo? (this 1 http://www.shapeways.com/model/1769084/62x20-rim.html?modelId=1769084&materialId=6 )

[efferman]

No, this is a four rim set.

[olaf9198]

Oke, thank you

[N-4K0]

Your custom u-joint looks very strong, Lego should consider to make them like that

[allanp]

The quality and strength of these parts are better than I would have thought.

[efferman]

we will see how they perform after some time of using

[efferman]

pins which follow the idea of D3K

pin a half and 3/4

[D3K]

Ah, brilliant! I had completely forgotten about that one! Don't think I have ever had the need for it again

Regarding the part; do you think it should have friction perhaps?

[efferman]

The parts will hold together but how much friction the pin will generate, i only could guess. A tenth more or less of the shapeways tolerance, will decide between friction or not.

Hi Effe

I ordered many parts, including differenet types of differentials, but shapeways canceled my most wanted diff 20Z 2L diff:

"After taking a closer look, we cannot print part of your order 456618, placed on 06/20/2014.

We’ve credited €17.49 to your Shapeways account for the following:

4 X Diff 2m 20z in White Strong & Flexible Polished designed by efferman - $5.00

Given the nature of 3D printing, converting digital files into physical products, every now and then we catch designs that would be too fragile to create in certain materials. Though we do our best to identify these issues as early as possible, some are only found during the manufacturing process. What you can do is:

Contact the product designer -- they can help resolve the issues found during the manufacturing process.

Your continued satisfaction is our top priority. If you have questions, or if we can improve your Shapeways experience in any way possible, please email us at..."

Do you know whats the problem?

May be I can order it only at my own risk (i mean they cant give any guarantees on this part)

Thanks

[efferman]

damn, why they are available in polished white? the problem is that the Pieces are to small for polishing. sorry for this mistake. for the 24 tooth 2m diff you have not get this message? it has the same internals, so you will probably get the same message

when you contact the people at shapeways and ask if the can modify your order in non polished white and flexible
