Maglock, Toddler Safety Lock For Cupboards

thingiverse

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 Fusion 360 project file is attached.
