This is my remix to the Magnetic child lock by bookmake.
This design requires no screws or anything, just stick it with easily removable double sided tape.
I changed the magnetic sizes to square 10 x 10 x 2 mm. Where the magnet of mag.holder is circular 12 x 3 mm (circular magnet weaker than the square one).
UPDATE:
Good Luck
