This is a simple set of covers for the knobs on the WinCtrl Boeing 737 EFIS that make them easier to turn for those with limited hand function. These are designed to slide on with a friction fit, no glue or fasteners required. I found that Bambu Basic PLA light gray matches the original knobs pretty well.

To install, simply push these caps onto the existing EFIS knobs.

I’ve also designed adaptive knobs for the WINCTRL Boeing 737 MCP, which can be found here.

I’ve included the .step files in case you’d like to modify any of these knobs to better suit your individual needs. :)
