I liked 3DBROOKLYNs Wall Bottle Opener but I had some concern about its durabilty. See my make of it for more about that.
In this design I made room to glue in a piece of metal (steel, in my case) that will increase the lifespan of this piece. It's meant to hold a piece of metal 32x7x3mm.
I also did away with the wall cleat and instead added a hole for a 4mm screw.
Since I only had 5mm diameter magnets on hand I also changed the size of the hole for the magnet.
I used Tinkercad to do some "meshmixing" on the model.
The author marked this model as their own original creation. Imported from Thingiverse.
