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
