Featured Thing!

Description

Sriracha AKA Rooster Chili Sauce goes well with everything, but waiting for it to pour is real drag. Not anymore!

DOUBLE the nozzles for TWICE the spiciness in HALF the time

Upgrade to the MOKO Bottle-Unthrottler and start pocketing the savings.
Now you can spend the hours of time saved doing the things you love!

My only concern is the rounded flange on the bottom gives very little adhesion room and my machine keeps getting mad about it sticking...otherwise great thing!
Such an awesome idea!
Has anyone tried printing 3 and connecting them to make 4 nozzles? You could doctor up 4 dogs at the same time! Sah weeeet

3 words. 7 minutes abs. In other words, why stop at 2 nozzles?
I don't see why you couldn't daisy chain them together for exponentially tighter abs. I mean, more sauce.
Is there a flow equalization valve built in?
Shouldn't it be "Twice the spiciness in the same amount of time?" It's more technically correct. Otherwise it's effectively being multiplied by 4.(Spiciness/Unit_Time)

This is the coolest thing I have ever seen.
Dude you have no idea how much I missed this invention. I will make a hotdog offer in your honor Sir.
This is a really cool idea, but I find the best nozzle is no nozzle at all. :-)

As to the food-safe issue, the real point is there isn't *any* 3d printer plastic that is *certified* food safe. Except possibly for Taulman T-Glase which is made from "FDA approved polymers" their nylon isn't. Even if the plastic were "food safe" in order to extrude a food safe item you would have to have everything that touches the plastic be "food safe" as well. So filament guide tube (if you have one) filament drive gear, hot-end heater and nozzle, the bed you print on all have to be made from certified materials and cleaned as if they where items in a commercial kitchen.

That said I think most people are way too uptight about "food safe-ness" but don't have any problem printing a whistle in ABS and handing it to a kid.

I personally get a funny taste from putting ABS filament in my mouth so I'd recommend against eating with 3d printed ABS for that reason. :-) I've not noticed any odd taste from PLA, Taulman Nylon does smell weird when hot but a hot teflon pan smells weird to me as well.

The real take-away is be smart and use common sense.

Too bad PLA/ABS aren't food-safe. Hopefully people are only printing this with Nylon 618 (the only thing close to food safe you can print with an FDM).
PLA is food safe, but most coloured PLA filament has additives added to colour it, and most extruder nozzles contain materials that aren't food safe, and will probably affect the printed object.

So if you're going to print anything that will come into contact with food, you should make sure you have the right materials for it.
First, FFF/FDM printing leaves small voids in all prints that are perfect homes for bacteria to grow in. Unless you finish your print with a laquer, etc, these voids make it unsafe to use more than once. And for anything to be food safe, the manufacturer must go and get it certified - unfortunately for 3D printing filament they'd most likely only have to certify the filament and not a printed part which would give people a false sense of security. This covers both ABS and PLA filament.

PLA filament softens and absorbs water especially if its heated at all (which is why things like this work: thingiverse-production.s3.amazonaws.com/assets/7d/20/21/46/67/spring_instructions.jpg) which makes me strongly doubt if its actually safe for anything that is used more than a single time.

ABS releases numerous toxic chemicals when heated, hence people talking about PLA being safer to print in an enclosed area. If you heat an ABS container with food/liquid on it it will leech these chemicals into your food (theoretically eating hot food off ABS can have a similar effect, to a lesser degree) which is why ABS plates are never microwave safe - which makes me again doubt that they are actually food-safe.

Nylon won't leech any chemicals (that I've seen) into food, so assuming you have it finished nicely (similarly to vapor deposition) it would then be food safe for more than a single use - This may just be personal paranoia, but its worth getting some perspective and additional info out there.
good info, I don't even like eating from food safe plastic. if it taste or smells like plastic then you're eating plastic, just like water bottles you leave in a hot car or that have been in the bottle for a long time. there's no shelve life on these products but there should be.

even if plastic is food safe, that doesnt imply that the processing equipment they are using, oils to keep the plastics from sticking to machinery, or any other of the thousands of variables in plastic making is food safe.

Any plastic out there that was ever considered food safe or tested food safe was done so by the plastics industry that are trying to convince you they are food safe and recyclable.
Shellac is generally considered food safe and is even rated by the FDA as being so. Apparently it is even edible and used in food products. I can't tell you what you should do for yourself and yours, but I use it on my own prints of childrens toys and kitchen items. en.wikipedia.org/wiki/Shellac
I hadn't previously looked into food safety issues in 3d printing, but I'm curious about your sources. Certainly disposable PLA cups are very popular and sold in many places. I've also seen ABS bowls and the like sold in stores, and a quick Google search yielded this result which reads in part: "Acrylonitrile/butadiene/styrene copolymer identified in this section may be safely used as an article or component of articles intended for use with all foods, except those containing alcohol,"

accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/cfrsearch.cfm?fr=177.1020

I guess the fine ridges on 3d prints could harbor bacteria, but Nylon would suffer from the same problem.
What brand PLA are you using with that printer? Does it print reliably? or does it clog?
This is just the attachment that I needed to cure my sinus condition. :)
but where do you get the extra nipple from??
Dude, my recycle bin has one a week. You probably don't need this attachment if you are snarfing down enough of the rooster to have an extra.
What?! you still ask that?!

Print it goddamit! :P
Please provide an STL for the nipple :D
Brilliant! I've oft lamented the time lost to applying copious amounts of sriracha to everything I eat. No longer must I do so.
Great idea! However, you have to remember that PLA/ABS FDM printing is NOT food safe. Please be careful so you don't get sick.
I printed one of these, and with the time saved bought a Lotto ticket that won.
Thank you Moko!
Wouldn't it be: "DOUBLE the nozzles for TWICE the spiciness in the EXACT SAME time" or, "DOUBLE the nozzles for the SAME spiciness in HALF the time" ??

Just messing with you :) Cool idea!
You took the works right out of my mouth! :)
jep. twice the spiciness in half the time would require 4 nozzles.
Print 3, and attach them all, no?
I always thought "there has to be a better way!" and here it is.
This right here is a game changer!
You Sir are a Genius! Bravo.

:)
