GM Lumbar Adjustment Knob

This is a Lumbar Adjustment Knob I made to fit my 2005 Chevy Colorado, but it will fit a variety of General Motors SUVs & Trucks from 2002-2012. These knobs tend to break through general use, so I designed this to be beefier than the OEM item, to compensate for wear & tear, as well as manufacture. I recommend using PETG or any other higher temp Filament, as PLA will warp and weaken from the heat generated from a car left in the sun.

I recommend a .2mm layer height, and 20% Infill
