The mini injection machine keychain was designed to 3d print without multicolor system, the files have the name with the color.

The "Red-Black" piece is for color change with pause in height, fisrt red and after black.

When we made it, we didn't like the logos (photos) and we removed them and now it's clean.

The assembly is easy and it doesn't have infill only it's the perimeters.

Finally, we removed the letters that you can see in the photos.
