Thank Flywoo for the Arm protector model - you can download that for free from their website.
Without these Skidpads / motor protectors / Standoffs (whatever we call them), the Explorer LR4 wobbles and lands on its Beeper. These make sure it sits flat and off the ground.
I added a custom Standoff / motor pad.
You need to mirror this print and print two of each.
TPU - 0.2mm layer height.
2 -Perimeters, 3 - 4 Top & Bottom layers.
No Infil required
Print upside down with Supports. - Takes a small effort to clean up - I use small nose pliers to pry the Supports off.
The author marked this model as their own original creation.
