It has always been impractical that the battery cover of the Stromer ST3 or ST5 does not remain closed when the battery is removed. With this holder, you can now keep the cover closed. And if it's not holding the cover, you can stow it away with the saddle mount.

You need some neodymium magnets.

• Battery holder: 4x magnets with 4mm diameter and 10mm length
• Saddle mount: 4x magnets with 5mm diameter and 8.47mm length

Be aware of the right polarization of the magnets! The magnet pairs are aligned in the opposite direction. It is best to hold them up to the connection socket on the Stromer to check the correct alignment before pressing them into the holder.

If you put them in the wrong way, you can use the holes and a 2mm allen key to push them out again.

The models are created with FreeCAD.
