xmaxx cush drive insert

hi guys so i have traxxas xmaxx and i noticed delay/wear in my spur gear shaft as ive ran my xmaxx for a while i inspected my cushdrive and as you can see it was past worn out so ive designed this insert which will act almost like stock which has been great for me printed in tpu so it still gives that flexability and durability still please share your feed back in comments be great to hear thanks.
