My traveling tractor sprinkler has had a hard life. The original wheels are sun-bleached and cracking/flaking and aren't much longer for this world. Since I just replaced the drive box and stripped most of the bright yellow paint, I figured it could use some new wheels too! This model is a direct replacement for the main wheels and doesn't need the retention cap. Its a snug fit over the shaft and a hard click to latch on to the pins.
Do reinforce the center hub where the drive pins transfer the torque to the wheel else it'll strip out. I used 40% infill and 4 walls on the center section. .25mm draft defaults for the rest! With Prusament PETG
The replacement front wheel I found on Thingiverse.
