added the part numbers (and I forgot to mark the gap, it exists)
the difficulty is that the two existing magnets 70023 and u9044 have to fit into the same part.
both magnets should be D10mm (25LDU), but dont match that.
top and bottom variants have the same small offset from magnet to rim, the center one has a bigger distance.
(would it be ok to scale the u9044 by 1.2 in length for the center one only?)
