This was a case for the magnetic latches on an older Gibbard China cabinet. There is another make on Printables but I found it was to large so had to design up a smaller one. This is basically as close to the original latch as I could make it.  This one is 45.5mm by 14.7 wide and 13.7 mm high. The openscad code is included, it is junky but gets job down. Printed in ABS because that is what I use. Because of the build supports that the printer adds it is a bit of pain cleaning it after the print but works I okay and I only had 3 to do. Cabinet is about 35 years old and Gibbard went out of business so good luck at find the exact same size.
