This is a small version of the fusion vibrator. The small fusion form for molding can be made with 3d printers with smaller volume. In addition the inlay for the body interaction development board is reduced in size, but there is still enough place for board and battery. Only about 120ml silicone are needed. The form was constructed in Tinkercad.
Modify the form in Tinkercad: all forms, inlay only, form only
Download the STL files for printing: round_something_06_final_inlay_improved. There are some artifacts but printing is fine on the daVinci 1.0.

Please follow the instruction from the large fusion vibrator. When you poor the silicone into the form it is very important to keep the USB connector free from silicone. Even very small amounts can cause the USB connector to break apart from the board. When the USB connector is broken then you cannot recharge the vibrator. Also be always very cautious when you plug-in or plug-out the USB connector.
Finally you can remove the overhanging parts from the inlay.
