I used kC's designs and combined the two parts to be a one piece skid and side arm protector. For me this requires M3x10mm bolts for my motors, yours may be different, please adjust accordingly.

I sliced this part using Prusa Slicer at 0.16mm and 100% infill, with supports. Printed with TPU. I should also note you may have to turn the part 180 degrees to print it.
