Instead of printing a vibrator case we construct a form for overmolding the body interaction vibrator development board. The updated overmolding process is described here

The case for the body interaction vibrator development board are printed with a 3d printer. There are two possibilities.
(1) You can use a printing service like Shapeway or Sculpteo. Sculpteo has the advantage that they offer food safe material. This means there are no risk if you apply the case to your skin or even insert the case. Follow this Link to the Public Sculpteo Library. The library offers 3d views, material, color, finishing configuration and price calculation (there are no surcharges for the designer.):
(2) You can print the design on your own 3d printer at home. If you don’t have one you could go to your next Fablab or Hackerspace and ask if you could us the printer. You need a STL file which can be downloaded from http://www.thingiverse.com/south/designs
After printing the case you can assemble the body interaction vibrator development board. In the blog you will find several videos which explain the assembling. For a quick reference please download our guide: quickstartguide-bodyinteraction1
We ordered the organic vibrator form from Sculpteo. They offer material which can be used for food – so it’s very safe.
All you need for assembly is the body interaction motion controlled vibrator development board and two M3 screws (about 6mm long).

Chain of Ball Vibrator design with cap
The new design catches the “chain of balls” design theme used in some sex toys. It was constructed in Tinkercad and it is really simple to do it on your own. This how-to video explains the construction in detail.
The design is composed from several spheres
Try it on your own in Tinkercad. Just grab a sphere, make a copy, resize the copy, make a copy again and repeat this until you have a chain of spheres. Now select all sphere and use the “align” tool. That’s it.
The tricky part is the screw cap. This is needed to enclose the body interaction vibrator development board.

There is new version of the vibrator ring. The height is smaller than in the original version. As there must be enough space for the vibrator development board, the LiPo battery and the vibration motor the case is larger in height. Board and LiPo are now beside one another. The new case is printed with the daVinci 1.0 3d printer with yellow ABS.

As alternative to the 3d printed form a flexible form made with silicone could improve the handling of the body interaction board (BI1) for certain applications. The vibration is more comfortable and less noisy compared to other cases. If you want to do it on your own follow this how-to.

Some adult toys are made of silicone or at least are coated with silicone. Silicone cases are easy to clean.
We have constructed a 3D printed form where we will fill in the silicone. The form comes in two parts that have to be fixed to one another by tinkering wire. In addition the board has to be hooked to the form. For this we use a USB connector which is plugged in the USB port of the board. Then the USB connector is fastened to the form.

Use a silicone which will become solid after moulding. This property of silicone is indicated by the shore A value. Silcone with a low value is flexible. We use silicone with shore A 43.
