Astra G, TS Astra Roof Rack Trim Clip - Easy Print

thingiverse

I recently had to remove the roof rack trim on my TS Astra (Astra G), which resulted in my clips all breaking. It's incredibly hard to source the clips, and they are something like $20+ per clip, which is a ridiculous amount for such a low price car. So I decided to design up the clips in FreeCAD. One of the issues with the clip design is that they are too complex to 3d print in a way that the stress lines aren't oblique to any print layers, so I designed up a version of the clip that is far simpler, but still works and can be easily printed on it's side with no supports and can still actually work as a clip. The stress forces don't work against layer adhesion lines. Again this needs to be printed in something that has high glass point temperature, as a minimum PETG, but more likely ASA. FreeCAD source file included.
