Bicycle V-Brake (Linear Pull) Mount Cover

I have a mountain bike frame which has both disc and v-brakes. I recently upgraded to disc, leaving the linear-brake posts exposed. The posts are screwed into the frame and easy to remove. That then, leaves a hole in the frame.

I made these covers to hide the holes for the v-brakes. These push into the hole and are held in with an M5 bolt, similar to a screw shield. They include an alignment tab which fits into the spring-hole on the frame to keep it from rotating.
