The original ground lip was quickly worn and started to disintegrate, so I thought I'd make a new one from TPU.
Printed in Fiberlogy FiberFlex 40D. Had to split the part into two halves as it was too long to be printed in one piece. The good thing is that if one side is worn you don't have to change the whole lip :)
Have not tested more than a few hours outside, but it seems to be holding up nicely.
The author marked this model as their own original creation.
