Spacer and Cover for hexagon Filament Shelf

You need the original Filament Shelf with heaxgon design from @Mechmaster

As I only had some smaller tubes with 16mm diameter I quickly designed a insert for the hexagon holes that fits to a 16mm pipe. (if you need a other diameter please feel free to contact me - I can create other variants too). 

I also added a closed version of the spacer that can be used as a cover cap. If you print it in different colors you can give your Filament Shelf a more individual look.
