This holder and cover are for a custom made low budget Primer Cube that uses a ZY6812 motor and a bowl shaped magnet array with 89 pieces of neodymium magnets.
The motor usually comes with a gear mounted on the axle which has to be removed first.

The magnet array uses 89 pieces of 10mm cube magnets which should be glued into the array.
