GM Body Panel Fender Trim Push Rivet Fastener Clip

Yet another push rivet, body panel fastener. These work by grabbing at various depths. It's not a particularly strong connection, but many plastic pieces in cars are held together using these types of fasteners. They are mostly one-time use, due to the design. Once you remove it, the ribs are basically destroyed. Luckily, we can just 3d print them.

I actually had to increase scale 10-15% to fit my Buick Lesabre perfectly. Scale as needed. Don't flip it upside-down to print or you will need to have supports for each rib, rather than just the top. Use tree supports, touching buildplate only, 45 degree angle max (hopefully, your printer can handle that), and brim/raft. Tree support just easily peels away.

UPDATE 5/8/2023: New rivet with bigger ribs. Some holes on my car were wider, due to age and abuse. Now perfect fit for my Buick Lesabre is about 90% with this new file. One plastic panel that was ripped out had a bigger hole, so 100% was perfect. As usual, scale to your needs.

PRINTING TIP: If you are having trouble with adhesion, drop the object 1-2mm below the build plate. It will give the rivet a slightly larger surface area to hold on to the brim/raft.
