M22x1.5mm Axle Thread Cover

This is an axle thread cover I made to help prevent rust when my vehicle is running winter tyres. This cover is for an M22 x 1.5mm thread. 

I recommend using PETG for this part. My experience is they tighten up nicely against the inner bolt, and the added grooves allow sufficient grip to torque tight by hand. 

Warning: Use at own risk and consideration of other drivers on the road. Be sure to tighten sufficiently to not come off whilst driving, and inspect to ensure they do not loosen over time.
