GM Blend Door Gear

I initially tried dvanommen's and it did work, though the dimensions were a bit askew. Outer gear's teeth mesh was a bit too tight and inner gear had some play.

This is a redesign. Outer gear (41T) is 25.5mm and inner gear (11T) is 9.6mm.
I tweaked the dimensions a bit to account for the uneven shrinkage of PLA. While the outer gear only shrinks by 2%, the inner gear is closer to 7%. These changes should make for a tighter tooth mesh and longer service life.
Shaft hole is also set slightly larger at 2.75 but may still need to be drilled out to 2.5mm once printed.

Should fit OEM GM part but if part is aftermarket fitment will be unknown.
