Getting rid of hardware parts smell (GT2 timing belt)

It's a garbage-quality belt, and it will probably continue outgassing at a steadily-decreasing rate for a very long time. The fact that it has a strong chemical smell is pretty good evidence that it ...

Has anyone used a Shield Buddy (en lieu of a Arduino Mega2560) as the RAMPS 1.4 host board?

It's not quite as simple as you would suggest. You can't just recompile Marlin for another device. You'd need to rewrite large parts of it. It may be compatible with the Arduino IDE, but that doesn't ...
