So after one year having this in operation, it seems to last just fine so here we go:

print the "WheelHubRepair" piece, PLA should work fine

you need two self tapping screws , length about 25-30mm in length, 3mm diameter. And a method to cut some aluminum or steel plate of 5mm thickness precisely. 

you need to modify the robot wheel:

  1. remove the black plastic cover of the wheel( 3 screws ) Note: you wont be able to put it back on. But it is actually not needed anyway.
  2. cut the plastic yellow wheel hub with the metal insert as shown in the picture
  3. use the mounted printed part to guide a 2.5mm drill bit, drilling through the wheel
  4. remove printed part and largen the two holes in the wheel hub to 3mm

then you need to cut two pieces of metal (steel, aluminum) and make them fit snug into the two printed wheel hub repair part:

  1.  cut two blocks of metal to size 14.5 x 9.5 x 5.0 mm
  2. make them fit nicely into the printed piece

mount the printed repair piece on the wheel, tighten the screws.
Put the wheel back on the mower, check if everything fits.
