New vibrator design for the vibrator development board & 3d cases

Chain of Ball 2

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.

Improved vibrator ring

Ring2_6There 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.

New organic vibrator design

organic_wide_-_hole_20_-_finalWe have two new vibrator cases for the body interaction vibrator development board vibrator. Both have organic forms. The difference between them is the thickness on the top.  Both version comes with a cap which are fixed with three M3 screws.

copy_of_organic_wide_-_hole_20_-_finalThey are constructed with Tinkercad. The design is still simple. The complete form is composed out of 9 half spheres.

Another difference to all earlier designs is a change in the inner hole form. It is smaller to fit better the development board.

Molding a silicone case for the BI1 board with a 3d printed form

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.

Comparing STL and SLS print technology

The encasement in the middle is printed in Stereolithography (STL) technology. In comparison the blue and red case is printed in polished Selective Laser Sintering (SLS). The STL encasement has a very smooth and soft surface and is even more solid than the polished SLS version.The STL looks rather matt compared to the shiny surface of the polished SLS print.…

vibration makes the mouse moving

  There are more interesting use cases for vibration motors. In this example a 3D printed mouse is equipped with the body interaction pcb board. The vibration makes the mouse moving. The mouse even manages to pass obstacles. On the bottom of the mouse the vibration motor is inserted in a hole. Then the pcb is build in and secured…
