Office chair crosspiece insert

My office chair with wheels was equiped with inserts, made from very poore plastic, very soon them broken. I can't find replace in stores, so 3d printer hurries to the rescue. I made a copy from originals with some improoves. My office chair use 10 mm stick wheels with snap rings. I made some versions to achieve tight fit, but becouse of bad quality of chair some times need to use file.

Inserts I have printed from PLA with 40% fill and it work good, inserts more stronger, that original ones.

I have no information about compatibility with other chairs, more that, i have no information about mark of my chair, it simple very chip offise stool, so, use my model at you oun risk.

If some need, I can provide original model for Fusion360.
