Remix of a Paper Towel Stand by Jonathan Levi that makes it possible to print it on smaller printers. The bigger is screwed in, the smaller part has a triangle-shaped part that acts as a guide. The clearance for this guide part is 0.3mm which should allow it to connect with the bottom part by friction. In case it doesn't - you will need to use a bit of CA Glue :)
Here you can see how the parts are connected:
