I made this to test material profiles before I re-ran the 1967 Shelby model posted on this site. I wanted to test unsupported bridging before commiting a lot of plastic and machine time, and this part helped me find and fix other issues too.

This part is drawn in millimeter units. The original Shelby is drawn in inches.

When I made it using 0.15mm layers, I set to two perimeters and 1mm thick caps.
