This particular design was inspired on the contests that were being run here. Unfortunately, my timing is horrible as I missed the cut-off. That said I'm uploading here and hope that you will find it of interest and download, print.
The image labeled Paper towel you will need to print twice, as well as paper towel rod, they are identical pieces so I figured I would save time trying to re-create then and just pass on the word here.
This was all printed with no supports, my prints came out looking great.
What you will need print wise:
(1) Shelve 1
(1) Shelve 2
(2) Paper Towel
(1) Paper Towel Connector
(2) Paper towel rods
The author marked this model as their own original creation.
