Windshield Wiper Plug

I recently worked on a 2015 Hyundia Accent cleaning it up for my daughter and noticed that it only had one plug covering the nuts that hold the wiper arms to the motor. So I got out my calipers and went to work designing new ones for it. I used concentric pattern for the top and bottom layers to give a nice even clean look to them. No post printing work is needed. Please print with top on build plate
