I needed a can holder without the supports or edges, to fix it directly to the wall or furniture.
I have remixed the model from Olo Deepdelver, removing the back edges, moving the screw hole and adding a small extrusion at the back just to be sure the support will not move and will be vertically aligned on the wall (I have printed the model with small support for extrusion to be sure it will not bend).
2x4mm holes needed on the wall, one for the screw and one for the extrusion.
The author remixed this model.
