Xhover R5LX/R5X Arm Bumper
Definitely some room for improvement here, but I wasn't going for perfection. This is my oldest 5" frame but it's still hanging in there.
I just wanted something that can take a few hits and help keep mud from getting up into the motors as easily.
Requires longer screws, obviously. TPU is 1.5mm thick in screw hole.
This is for the 3mm (actually more like 3.3mm) arms!
V2 now has protection for screws when landing on rough surfaces and just more protection for the bottom in general. Not as useful if you only fly over grass and weight is more important, so I left the original version too. V2 is best printed with the ball side up. V1 is best printed with the flat side down.
