Lawn mover plastic wheel

Lawn mover wheel 18cm diameter 5cm width. My previous wheel is on the image, easy to broke, crack under pressure and sink in the wet ground. Central area is full profile, so in the center hole can be enlarge depend of the axis diameter ( my is around 14mm ). Added crampon to see if it will be easier to stay above wet ground and not to lay down grass when lawn mover pass over it. If someone have printer and try this wheels please let me know! I do not have 3D printer to try by myself. My previous wheels were 4cm width so I expand this one to 5cm width. I hope you will like idea. I wanted something that is necessary for everyone and useful. Files are free for any changes or commercial use. Cheers grass cutter colleagues :((((
