NOTE: As of today, Jan 22, 2024, new versions (v1.2) of both the cradle and case bottom, have been published on the Printables listings, which were modified to have the magnets glued in from the reverse sides, so a magnet’s grip from one side can’t pull out the corresponding magnet from the other side. Both magnets will pull each other “into” their sockets instead of “out of” their sockets. (They pull through thin layers of printed plastic.) The magnetic grip is slightly lessoned, but adequate, providing the magnets are firmly seated into the sockets. Below is a link to the new version:
