I've tried the straw method, shaking, steeping. I like mixing and steeping, but mixing with a cut straw is a pain in the ass at best. Especially with multiple flavors. I wanted something simple to use and easy to clean and it needed to fit inside most ejuice bottles without hassle. The rod is 12cm long and the star shaped mixer is 1cm tall and 1cm in diameter. The rod is 3mm in diameter so it will work with a drill or dremel.
The is my first go at 3D designing/printing, if you have any feedback or can improve on it, please feel free to do so!
There is no fee added on, the shapeways link is at cost. I think mine was about $7 shipped.
Cheers and I hope someone else can use this as much as I can.
If you made one that was much larger in diameter for mixing big batches, I'd be all over it. But this is definitely cool.
I can do that pretty easily and I'd like one of those too. What dimensions were you looking for?
I need rod length/diameter and stirring star diameter and height.
hey, Thanks!! I have a crappy hobby drill press, [prob harbor freight circa 1988] that I'm throwing a pot on to slow it down... I haven't even gotten to the stirrer yet, and was going to slit a soda straw up-- this is a much better idea! But I'll make a tiny one, because I use smaller bottles that won't fit 1cm in the neck.
It is super easy to modify the dimensions. You can download the file at the link in the first post and then edit it using www.tinkercad.com. It runs in your browser. The send the file to shapeways when you are done.
I might scale it down AND reduce the mass of the rotator to be 2 sets of straight blades, because [small bottles and ] I am thinking this is much like a hand drill paint mixer attachment I have, where the blades are like a X at the bottom of the shaft -- am thinking some R+D must have gone into the design, and paint has similar viscosity. I was going to do something with stainless wire, like a tiny whisk, but now I have something else to try. Thanks for posting this...!
FYI, a Dremel brand rotary tool will spin at up to 35,000 rpm. Only the higher end models have variable speeds and none of them will go below 5000 rpm. I'd be surprised if a long plastic rod like that could handle those speeds.
Modified the stirrer into a cross. I think it will mix better than the star pattern.

Hey, this is a great start, but you might have far superior action out of this stirrer if you angle the cross members. Think of the blades of a fan. Spinning the fan causes air to move in a direction, instead of just try to get out of the way. This picture should help illustrate what I mean.

So if you rotated the 'blades' by a couple of degrees, the spinning action would cause the liquid to flow in the downward (or upward) direction, and since it's in a container, that will cause a current to form in the liquid, facilitating much more rapid mixing.
