MTB Chain Guard

I designed this thing for my wife's bike, which was missing a chain guard to protect pants from getting dirty by the chain.
I fits a 5-hole 110mm diameter chain ring with approx. 65mm between the holes.
The chain ring here is a Shimano Deore LX.
The guard is fixed to the chain ring using self-fitting pins and the Inbus screws of the ring. It holds quite tight! :-)
