SUPPORT FOR FLEXIBLE DENTAL FLOSS

This is a project I had developed some time ago. I wanted a stand to floss make it as simple as possible, easy to wash s why no parts or devices. But how to develop this support, and would have to hold the floss tightly on the ends of it, so it could be used?
The solution was to take advantage of the flexibility of plastic. Thus, the two ends of the floss can be attached by the cord holder, ie, puts up the two ends of the wire in the middle of the cable, which is broken into two equal parts. When the person holding the bracket cable to use it at the same time is holding the two ends of the floss, simply squeeze it a little more.
Thus unable to develop supported in a single piece, and yet functional, taking advantage of the flexibility of the plastic which is the material has to be used.
Despite having developed the computer, I had to manually shaping the piece by hand in epoxy putty. After the copied part in resin using silicone molds. It happens that the resin loses its flexibility over time, s why it was not the right material for this support.
Now in possession of the printer Makerbot, redid the project on the computer, based on the last model produced by hand, as were several models initially, and got this, which besides being robust is anatomical, and small. For that reason they are comfortable to pick it up, and easy handling.
Naturally, there are several types of disposable floss holders, but there are still wanting to floss, so much that is still on the market. Moreover, these disposable media are more expensive, and are not comfortable to take them, because those round cables run in the fingers, and these must be hurt because squeezing harder, and are nothing anatomical feature by itself to be disposable.
But only use the floss is not convenient because it gets dirty hands and there is a certain difficulty in flossing teeth at all, having to put a hand on his mouth. Hence the need for a support for the dental floss that is simple and easy to wash.
Pity that now I can not use the printer Makerbot because it is having connection problems with your computer. For that reason they, the photo is the model I had produced artistically. In the main photo that appears, I made a montage to show their fucionalidade.
I offer support with two options to hold the floss between the cable division in two parts: first, this division presents smooth, and the second, with some ripple, aiming to give more efficiency to hold the floss.
I do not know how to behave in the two cases. I imagine that in the first case, on the flat, the two ends of the floss will be easier to put in, but require a little more pressure to arrest them. And in the second case, with the split corrugated, there is some trouble putting the floss between them, but it will be much more efficient in holding the two ends of the floss.
As I have no way to test it due to the problem of my printer, falls to those who download the files to be tested.
Who can, if possible, please send me a photo after they produce in their impressoras3D, so I can exhibit at Gallery Thinginverse.

Changes in support for flossing in 19/08/2014
At the request of Stef suggested that a change in the support flossing, to make it more efficient to hold the floss, introduced some modifications accordingly.
The suggestion that was given is to add a button below the U-shaped portion, where the floss was wrapped, and thus be more effective in arresting him.
I thought of this suggestion, but found that putting a button on that site could disrupt the movement of the support inside the mouth, beyond that, could not be hygienic because the thong would look all luscious saliva. And then, one more element that location could be the focus of impurities.
Even so, I found a good suggestion, and decided to think how could using this suggestion, arresting more efficiently floss in support.
The solution was the following:
The button that the person suggested in part that would be introduced into the mouth, under the two ends, I put the tip of the cable (3), the outside (see figure ...).
In another part of the cable, insert a hole (1).
Made a slot (2) in the cable that goes from the knob, starting from the end and through the other side of this button (4).
Thus, when flossing this modified support, the person would make a knot at one end of the floss so that when passing the other end of the cable into the hole, it would be locked, and then the other end would the two tips support, return to bibartido cable, screwdriver and pass on the button, then it could be rolled. One or two turns is sufficient. The tip of the thong would be left, the person would hold with your thumb when holding the cable.
Surely with these modifications, the thong would be firmly attached in maintaining tension while doing the cleaning between teeth.
Stl file added to the modified support and in the blend form.
