Magnet Clasp for 30mm straps

Had the same issue as the original designer(s). One of the connection of the clasp of the transport rack on my daughters bycicle broke. Use this design from @xtramp and modified it to fit the 30mm straps and different magnets (3mmx3.5mm diagonal x height). The holes need a little drilling after printing, but this way the magnets could be pressed in tightly.

I used galaxy black PETG for this print.

@JLmike7 thanx for the original design.
