iFlight XL5 XL6 XL7 motor arm protector

For my iFlight XL5 I need a motor arm protector for indoor and hard surfaces.thickness of arm is 4mm. I prefer to change the protector without loosing screws, so I designed it from scratch for using zip ties. That's also my first design with Fusion360, as my old program 123D is not supported anymore. Hope it works same with XL6 and XL7. Please confirm.
Printed with TPU, 100% infill
