Magnetic door stop - steel doors - TPU center section

I needed a door stop that was easy to use because my walkout basement door is pretty high off the ground due to the footing. So I came up with this. I used 5 10x3mm round magnets because I had a bunch. Super glued them in. You could also use it on a wood door by attaching a large washer to the door side. I printed the coupler center section out of TPU to keep it from getting broken so easily. Uses a M4x40mm screw and nylock nut. I included 2 lengths of couplers based on how far your door is from the wall. Also, included the STEP file so you can adjust it easily.

All print without supports, PLA is fine. Printing the coupler from TPU keeps it from breaking due to strikes.
