80/20 1020 Aerodynamic End Cap

This is an end cap for 1x2 aluminum extrusions from 80/20. This is to fit the 10 series size. It's best to print this on the side so the print layers run the length of the tabs that slide into the extrusion.

This was made originally for a roof rack. Free build plans for the roof rack are available here: https://www.instructables.com/id/Better-Faster-Stronger-Build-Your-Own-Automotive-R/

Let me know where you use it! :)
