Xmas Tree Base Feet

This might only work for mine but it works well and I feel my base is fairly common. The width of the bracket is 40mm and the overall width of the bent metal pads on the floor is 48mm. This should work if yours matches this description. You just slide these from the back. The picture is the type my stand is. I printed this in TPU on my sloppy ender3 with no issues. There is a screw hole provided if you want to screw it on.
