The “ball revisited” silicone molded vibrator uses a wireless charging module. Unfortunately there are different version available. The version with some textile like cable jackets have a different inner radius of the receiver coil.
We have changed the mounting on top of the picture as this type of the receiver coil needs a little more space. In addition the encasement is a bit larger. 
There is enough space for the body intercation board (top), wireless charging board (right) and the LiPo battery (below).
Finally the wire of the vibration motor is glued in the middle of the encasement.
Please follow the “old” instruction – nothing has changed. When printing out the 3d parts use the new version 4 of the inlay. All 3d printing STL files at Thingiverse
