Simple Door Stop

<p>I needed a door stop for an old, interior door. It replaces a wall-mounted rubber-ended spring that broke. So, I wanted this to be springy so it won't marr-up the base-boards. This was my solution. It uses a tensioned “jaw” to firmly hold to the bottom of the door. The tension is maintained by the jaw angling in some 4 degrees into the door and some radiused corners to avoid stress fracturing in the part. Printed in PETG to avoid PLA's deformation creep, I've had this in service for over 2 years (going strong!) and its met all of my objectives:</p><ul><li>Prevent the door knob hitting the wall</li><li>Don't marr up anything</li><li>Don't crush the hollow door</li><li>Don't fail over time</li></ul><p>My door is 34mm thick. Yours may differ, so, I'm including the STEP file so you can tweak to your needs. Enjoy!</p>
