Wheelchair replacement footrest band

I couldn’t find a replacement band for my mother’s wheelchair, so I modeled and printed one myself. The second band in the back or left in the photos is the original broken footrest band.
The wheelchair is a lightweight Excel van Os.
The diameter of the two holes in the band is 12 mm, depth is 18-22 mm (tapering).

I used semi-flex PLA from Real filaments. Printing was tricky, but slowing things down to 20 mm/s helped.
