This is a very simple toilet paper stand storing a whole package (up to 10-12 rolls) of toilet paper rolls. Refilling threading new rolls on the loose end of the bent iron bar. Empty rolls can be simply ripped off and the next roll moved to the uncoiling position. If there are less than 2-4 rolls left a new package (8-10 rolls) can be bought. In that way the toilet paper stand never rans out of paper.
Thanks to Amir for helping me with welding and thanks to Anna for help with 3D rendering!
