Toddlers love to play with folding closet doors; but pinched fingers send parents to buy safety locking devices, sold everywhere. But what if the sizes in the store don't fit your door?
Here we have a safety lock, similar to those sold in stores, customizable for the thickness of your door.
Thank you, Jigar, for the concept, design and test help, and photos!
In the OpenSCAD file, adjust variable door_thickness per your door's measurement, and variable with_felt according to whether you intend to line the inside with felt to prevent scratching the door; then generate your STL and print.
