KTM 790/890 adventure mudflap hole plug

KTM 890 Adventure has annoying issue. The hole in the rear mud flap does not make sense and just lets mud spray through and cover the rear light. This reduces safety even after light off road riding. it definitely needs to be covered. so, here is the cover.

designed this part over a 3d scan, so it fits tight and doesn't need any adhesive. though i have not tested it thoroughly. 

The part has a pin. to secure the fitting this pin can be melted with lighter and bended.

adding STEP file so you are welcome to further modify it.
