My wife drinks coffee on the way to work every day, so she has travel mugs that wont fit in the original Dosermaschine. I copied the back part of the base and added ever so slightly larger holes because my printer isn't quite as clean as the OP's.This sleeve allows you to use the travel mugs that fit in your car's cup holder.

The next part to tackle was the fact that the Nescafe jar she has was larger than the one @Wiesolator modeled his from. So I enlarged it and printed a prototype (as seen in the picture) to make sure it fit. After that worked, I trimmed it down to fit properly on the ring and look cleaner. I will print this once I get more black filament.

With both parts, mine wound up being 19.25 inches (48.895 centimeters) tall, so it JUST fit under the kitchen cabinets.
