These are magnetically actuated drawer locks.
8mmx3mm magnet gets pressed into slot in 'Lever'
3/16"x1/16" magnet gets pressed into slot on bottom of 'Housing'. Make sure you orient this so it pushes the lever up. There's a hole on the opposite side to push the magnet out if needed.
3/4"x3/8" magnet used to unlock -- just put in front of the lock on the outside of drawer (seen in 4th picture)
1.58"x1.58" 3M mounting pads to stick the housing to the inside of drawer -- cut a hole or leave backing on area where the 'Lever' contacts the adhesive.
- A #14x3/4" nail (or longer) to push through the housing and lever. It press fits in the housing and the lever rotates freely on it. I only had 1.25" length on hand so I just cut to size.
To stick the 'Catch' cut a piece of adhesive pad to size.
The catch mounts on the bottom of the drawer hole in the cabinet. Line it up in the center, stick it, then mount the lever/housing assembly high enough so the lever will snag on the catch.
Three perimeters for strength, supports where necessary. If you print these in a different orientation they may undesirably shear, however, in their current orientation my almost-two-year-old hasn't been able to break them.
0.15mm layer height for "top" & "bottom" parts, washer is fine with 0.2mm layer height.
I basically copied ''Enovoe Magnetic Safety Locks' that I purchased on Amazon. They worked great and we needed more so why not see if I can print them?
