There's so many door stops out there for download, but I decided to make another one for the pile. This one is a little more “Heavy Duty” for those heavier industrial doors, like freezers, emergency exits, etc. but can definitely be used for your every day house doors. Printed in TPU with a .2 layer height, and the print profile provided, this door stopper is STURDY with very little flex, but soft, so it shouldn't do any damage to the door. Designed to be used with shallow doors close to the floor and raised doors that most doorstops just cant stop. I haven't tried it on any Heavy Metal doors yet, but I'm sure it will hold up. Let me know if there's any issues.
