Door Stopper Replacments (Customizable)

This is a five minute design to replace the old door stoppers used for stair gates and on doors all over the place.

As you can see on the provided picture, the original version was in some ugly dark grey. The color did not change over the about 45 years, those bumpers where installed, but they lost their flex. The plasticizers inside evaporated over the four decades making a bump almost as hard as hitting the wall itself. Not do mention the wobble sound the doors made on hard impact. Since the bumper mostly lost its flex it started to crack as you can see on the images.

Since I like the simplistic 70th design, I myself designed a similar replacement part using the given measurements, but as always the FreeCAD source is included, so you can adapt the design for your needs.. Make sure you use 0.19 or up to be able to modify it.

What is nice about this simple design is, that you can mount it to walls, the floor or even the door itself.
