These cover the sharp edges and bolt on the front wheel of wheelchairs. These are pretty universal, scaling in size is usually all that is needed to fit the different wheelchairs. The second STL has a flat surface where a felt pad can be put for further protection.
There is a grove for a tie wrap to hold them on. You may want to print two the way they are and then mirror 2 for the other side of the wheel.
