Always-Open Invisible Doorstop ™

thingiverse

You ever encounter auto-closing doors that refuse to stay open? Your solution is here, available in all door sizes, and prints in just 15 minutes! Simply place the Always-Open Invisible Doorstop on the leading edge or top of the door and you're good to go! It works by wedging the door far enough away from the door-jamb that it won't allow the door to latch. The spring-arm keeps it in place on whatever edge of the door you choose, sliding off and on easily. *: Times may vary based on settings. **: Not actually trademarked.
