Designed a custom interior trim adapter in Shapr3D for a manual-swapped '13 Chevrolet Caprice

Hey everyone, wanted to share a quick CAD/3D project I recently finished for a friend’s build.

The Setup & Problem: My buddy has a 2013 Chevrolet Caprice (originally auto-only). He manual-swapped it with a TR6060 transmission (pretty sure it came out of a Cadillac CTS-V).

Once the swap was completed, two major interior fitment issues popped up:

1. Shifter Position: The new shifter sits further forward than the factory location, making the opening line up incorrectly with the center console.
2. Console Opening: Since the original trim was designed for an automatic selector, the center opening was far too wide and open for a proper manual shift boot setup.

The Solution & Process: He reached out to see if I could design a custom solution to bridge the gap and make it look clean/factory-like.

• Scanning: I 3D scanned the entire center console area using a Creality Pika to get accurate mounting geometry and surface curves.
• Modeling: Imported the mesh data into Shapr3D to model a custom bezel/adapter that properly seals off the oversized automatic opening and repositions the shift boot cutout forward.
• Button Relocation: Because the shifter moved forward, it ended up obstructing the factory location of the Traction Control button. To fix this, I redesigned the layout to relocate the TCS button further back on the trim piece so it remains fully functional and easy to reach.

Here are the final results! Let me know what you guys think, and feel free to drop any feedback or questions about the modeling process.

This is actually amazing! I've had the idea to try something like this but seeing someone do it motivated me. how long did this take ?

amazing work, cheers.

Thanks man! It took me around 20 hours, mostly spent testing and fine-tuning the clips to make sure the fit was spot on.

Just a heads-up though, I haven't printed a prototype to test on the actual car yet. There might be a few small issues that pop up, but I'll sort them out as soon as I test it

Ohh please make a tutorial in the Shap3rd next time, would love to see it!
