10mm Automotive Body Trim Rivet
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
I had a bunch of broken rivet teeth, some missing male rivets, and needed to finish a car repair late at night after the local stores closed. So, I decided to model both parts of the rivet so I could reassemble the trim panels.
This is a nearly exact knock-off of the rivets from a 2016 Subaru, but will work for any car requiring a 10mm (3/8") fastener. These parts work interchangeably with their counterparts that came with the car.
UPDATE: a 3-tooth version of this has been created. It is based on the same exact model and is stronger because each tooth has a larger connection to the base. checkout the part at: https://www.thingiverse.com/thing:5219386
UPDATE
Printing Considerations:
The female prints best on its side for strength at the base of its four teeth and will require some build support for such in your slicing program.. Printing it upright is easier, but the strength will be lost, and subject to the layer-to-layer bond strength, and the teeth will easily break.
I use Simplify3D for the ability to customize support structures.
The female part seems to print better rotated 45 degrees so that two of the edges of the teeth are parallel to the bed and the narrow part of the head touches the raft/bed. Look at the image with the support and see where the head contacts the bed/raft. Also seems like printing at 0.1mm/layer is counter productive and 1.5mm or thicker is better. This part prints more reliably with a raft under it to anchor the narrow…
