HOWTO: Front under body shield repair.

I have an '08 F430 Spider with skid plates to protect the bumper / front underside. Unfortunately, even with this there are occasional scrapes and bumps.

Overtime this has cracked the flanges on the bumper that the under body shield bolts to (see Picture 3). There did not seem to be an easy fix for this, and it annoyed me, so I finally decided to do something about it.

I fabricated 2 hockey puck type widgets (Picture 2) on a 3D printer (Picture 1).
I raised the front on jacks (haven't been able to justify the space for a lift yet) and removed the shield bolts, then placed a puck in each corner. The cut / slice out of the cylinder allows it to nestle into the corner of the frame (although I ended up trimming off the corner for the passenger side to make it fit better (Picture 5)), placed a bolt through (Picture 4) and tightened it up (unfortunately I forgot to take an installed picture, but it is all flush and the gap is gone).

The puck itself was fabricated out of ABS with 50% fill (see Picture 6). If I were to do it again, I would make them smaller and trim / bevel the corners more.

The last picture shows the tools needed -- 10mm socket, small tap (although just drilling the hole slightly and then torquing the both through would probably also work)
