Going to run into some delay, the printerguy changed the material to Colorfabb XT because he (guy is nice enough to think ahead gotta give him that) figured fuel + ABS may not be the best idea. Unfortunately heat resistance of this XT material is lower so I wouldnt want to try that as a first option. The order was already accepted and paid for because I noticed too late so I'm waiting for his response. I hope to have the parts in my hands before saturday.

Obviously we're going to add a chemical test to the list as well.

First off I'd like to thank everyone for the work they've put into this and for helping me save some money. Secondly, I don't think fuel goes through this part, it's a vacuum for air.

Yes I figured there is no liquid fuel going through. However it does not seem unlikely that (some) fuel vapor goes through it so something thats not fuel resistant may not be a good idea. I think we will be fine though.
I just had confirmation that they indeed are going to be produced in ABS so we are going to see the products very soon.

And for me its not just about saving a fellow motorcyclist some money. Its also about trying out some new things with new technology and supporting the substrate for whole 3D printing business to grow on. I guess there are few inventions in the world that became a common thing without being profitable. And for something thats still very rudimentary like 3D printing still is, new and usefull applications are required to keep this thing going.
If we succeed in getting a functional part out of this we could cut down cost of something with as much as 90% which is pretty crazy. People will become more aware and start coming up with more clever applications for 3D printing which is an incentive for improving the technology. Who knows where we could end up.

I have an ideal.

what if you used polychloroprene under the nipple? [neoprene] its stable around gas. I believe its not good around super high octane but if you put high octane in your GS, you're insane. 

Kap! .. I have a question,  since you mentioned molten plastic/abs before. .  And then printed in steel etc. ... molten steel? That's a fair bit hotter than the plastic. ... so. .. same machine type?  Or is the steel printing version the 'bigger industrial brother' machine?

Ask because you are currently one of the few people in regular contact? with this tech .. and we 'the plebs' are lacking understanding!

This should get you started

Shapeways steel printing

Shapeways nylon printing (like the throttle clip in the opening post)

Ultimaker printing (what is going to be done for me now)
https://www.youtube.com/watch?v=nk_8IcBVkRA

Or Walker? .. what say you? .. (sorry couldn't remember who else while I was doing prev on phone/tapa)...

Do they have different size/type machines for plastics/steel/glass?  .. can they do glass?

Ooh vids! .. watch when home again. . Or it will burn my phone data up!

I believe shapeways offered glass a while back but I don't see it available anymore. Its possible for sure.

This thread should be stickied.

Could you print me an entire, working GS, and give me the pricing on it?

That's how the regular GS is made innit
Cool.
Buddha.

Noooo.... c'mon Buddha!  Random parts bins!

Got a call from my printerguy today because he was really worried about printing it and its functionality when its done. Apparently printing ABS is a Buddha Loves You because you need to run it very hot (260 degrees C), while the printbed is about 100 and everything in between is pretty much roomtemperature. This can cause the plastic to shrink, deform and crack. He was also worried about the airtightness because I told him why the nipple had to be printed upwards, what its for and everything. Apparently the products are not always airtight. He is still going to try though and hes also going to print me a set in some PLA/PHA material just so I can see the difference!
If the material is not airtight I believe it should not be hard to fix with a simple surface treatment (e.g. submerge it in your wifes nail polish remover or something else like that).

I do a lot of prototyping with 3D printed parts where I work, and it isn't uncommon for us to do a light sanding and use epoxy and/or a shellac or polyurethane (or even just paint for less-critical applications) to seal it pretty well and make it perform a bit more like an injection-molded part--although I cannot speak to performance at high temps, mechanical properties slightly improve. Here is a quick link I found that may be helpful:

EDIT: Hydrocarbon exposure being a concern, you may have better luck with nylon 6/6 (although after a nice thick surface finish with polyurethane, who cares!). Although printing ABS is more difficult, as long as it's done relatively well, you'll be thankful for the toughness advantage over PLA, which tends to be more brittle but has better printed part dimension stability.

wouldn't it be possible to drill the nipple hole afterwards?  That might make manufacturing of the part easier

The hole itself is no problem at all so there is no need for that.

If you want the hole to have really exact dimensions, another technique we use is undersizing the hole by somewhere around half the filament thickness (on perpendicular holes). That way, you can take a sharp drill bit with your hand and finish it off exactly to spec in critical areas. The printing at an angle technique to get the important hole perpendicular is spot on! Although your mounting holes may come out a little goofy looking, undersizing a little more than normal will get you a nice round drill hole.

If anyone needs a part modeled in solidworks or some design advice for strengthening (with gussets, etc.) I'd be happy to help! Like I said, I do this sort of stuff for a living, just not usually on motorcycles  mostly big ol' machines.

b-but arent our m-motorcycles big machines then 

Being under 6ft/180lbs myself, the little 500 is plenty big for me!

Ah what can I say, not much I guess. I'm 6'5 hehe.

Just got the message that the parts are printed so I'll pick them up tomorrow. He didnt print them in PLA/PHA because apparently the straight up ones came out good!

Even got myself a preview:
