Summary

Lock for cupboards that gets unlocked by a magnet. This makes cupboards toddler proof. I use it mainly in the kitchen, where the little dude often made a mess by emptying the bottom cupboards.

BOM:

  • 2 Neodymium magnets 10mm * 10mm * 5mm
  • 2 M3 screws, 18mm length
  • 3 4mm wood screws, length at least 10mm

Instructions that worked for me:

  • print all parts
  • assemble all parts (should be self explanatory), put the magnets to place (glue them if they are to loose)
  • screw the hook with hinge to the door at the desired height
  • screw the latch inside the cupboard: the middle of the screw rail is 3.5cm from the door plane away. Measure this distance and screw one screw to the rail, semi fixed.
  • adjust the latch to fit the hook and test
  • screw the second screw to the latch to fix it permanently

Thanks to Non-ICE for the good basis. My changes to the original:

  • latch and hinge axes reinforced by M3 screws, threads modeled
  • washer to hold the hook in place (don't use a metal one, it will interfere with the magnet on the hook)
  • screw rail on the latch part
  • new ergonomic key
  • minor changes to dimensions, e.g. tighter fit for the magnet in the hook
